Beam Categories

Hand-Hewn, Sawn & Box Beams

The three primary categories of reclaimed beams each offer distinct aesthetics and performance characteristics. Choosing the right type depends on whether your application is structural, decorative, or both.

Hand-Hewn Beams

Shaped by hand with a broadaxe, these beams carry the visible tool marks, irregular facets, and organic character of early timber framing. Each beam is one of a kind.

Key Characteristics

  • Visible axe marks and adze texture
  • Irregular cross-sections add visual depth
  • Typically oak, white pine, or hemlock
  • Usually from older barns and frame buildings

Best For

Exposed ceiling beams, mantels, decorative headers, restaurant and retail feature installations

Sawn Beams

Mill-cut timbers from early industrial buildings, grain elevators, and rail depots. Straighter edges and more uniform dimensions than hand-hewn, with the same old-growth density.

Key Characteristics

  • Circular or band-saw marks on surfaces
  • Relatively uniform cross-sections
  • Commonly Douglas fir, Southern yellow pine, or oak
  • Usually from industrial and commercial buildings

Best For

Structural applications, post-and-beam framing, load-bearing headers, pergola construction

Box Beams

Hollow beams built from reclaimed planks around a lightweight internal frame. They give the look of a solid timber at a fraction of the weight, for ceilings where the beam carries no load.

Key Characteristics

  • Made from reclaimed planks
  • Fraction of the weight of solid beams
  • Can be built to suit a space
  • Can wrap existing structural elements (steel beams, LVLs)

Best For

Decorative ceiling beams, beam wraps over steel I-beams, light-weight installations where solid timbers are impractical

Dimensions

Common Beam Sizes & Uses

Reclaimed beams come in a wide range of sizes. These are common sizes and typical uses, and what can be sourced depends on partner suppliers. Always consult a structural engineer for load-bearing applications.

Size (Nominal)LengthsCommon Applications
4 x 66' - 14'Mantels, decorative headers
6 x 68' - 18'Posts, porch columns, furniture
6 x 88' - 20'Floor beams, headers, decorative ceiling beams
8 x 88' - 22'Primary beams, post-and-beam framing
8 x 108' - 22'Long-span beams, ridge beams, heavy headers
8 x 1210' - 24'Major ridge beams, heavy commercial headers
10 x 1010' - 24'Major structural elements, commercial applications
10 x 1210' - 24'Large-span beams, commercial builds
12 x 1210' - 28'Statement beams, large-scale commercial and industrial
12 x 1612' - 30'Major commercial spans, timber-frame ridges

Lengths are a general guide. Load capacity depends on species, grade, defects, and loading conditions, so have structural beams engineered by a licensed professional.

Provenance

Historic Beam Origins

Reclaimed beams come from many kinds of older buildings. Here are common sources, with the species and character typical of each.

Milling Buildings

Minneapolis grew up around the mills at St. Anthony Falls, and mill buildings used heavy timber framing. Beams of this type often show saw marks and bolt holes from machinery mounts.

SpeciesDouglas Fir, White Pine

Dairy Barns

Often hand-hewn with visible broadaxe marks and adze facets. A favorite look for mantels and ceiling details, with organic, irregular cross-sections and deep patina.

SpeciesWhite Oak, Hemlock, White Pine

Railroad Depots

Mill-sawn with dense, tight grain from old-growth timber. Exterior faces may be stained, while interior faces can reveal amber heartwood when cleaned.

SpeciesHeart Pine, Douglas Fir

Grain Elevators

Long, straight timbers with heavy saw marks. A common place to look when a project needs length.

SpeciesDouglas Fir, Hemlock

Industrial Warehouses

A mix of species depending on era and region of construction. Often show details like iron rod holes, pulley grooves, and paint shadows from signage.

SpeciesMixed: Fir, Oak, Pine, Hemlock

Churches & Schools

Often well preserved because they stayed indoors. May have decorative chamfers, routed profiles, or original stain still visible.

SpeciesWhite Oak, White Pine
Lightweight Alternative

Beam Wrap & Faux Beam Construction

Box beams deliver the look of a solid timber at a fraction of the weight. Built from reclaimed boards around a lightweight internal frame, they can be hard to tell from solid beams once installed, and they are much easier to handle.

Box beams are the practical choice for ceiling applications where structural support from the beam is not needed, for wrapping steel I-beams and engineered lumber, and for installations where weight limits prevent the use of solid timbers.

Construction Method

Reclaimed boards are mitered and joined around an internal lightweight frame, typically 2x4 or 2x2 furring. Three-sided for ceiling-mount applications, four-sided for free-standing use or wrapping existing structural members.

Wall Thickness

Usually the thickness of the reclaimed boards used. Thicker boards give a more convincing look at exposed ends and corners.

Weight Comparison

A solid 8x8 oak beam 12 feet long weighs roughly 230 lbs. A box beam of the same outside size weighs a fraction of that.

Size Limits

Box beams can be built to many dimensions. Length is usually limited by the longest boards available.

Installation Advantage

Lightweight box beams can often be handled by two people with basic scaffolding, without a crane, telehandler, or rigging equipment.

Steel Beam Wraps

A carpenter can build a box beam to wrap existing steel I-beams, LVLs, or glulam beams. The reclaimed wood shell conceals the modern structural element.

Surface Treatments

Surface Finish Options

The surface treatment defines the visual character of a beam. From raw patina to smooth-planed contemporary, here are six common options. Ask partner suppliers what is available.

As-Found (Natural Patina)

The beam surface is left exactly as it was recovered from the original structure — weathered, tool-marked, and bearing the full history of its prior life. Only loose debris and dirt are removed.

Best For

Rustic interiors, barn-style homes, restaurants and breweries seeking maximum authenticity

Hand-Hewn (Preserved)

For hand-hewn beams, the original axe marks and adze facets stay in place while the surface is cleaned of dirt, cobwebs, and loose material. The tool marks are the character.

Best For

Exposed ceiling beams, feature mantels, traditional timber-frame aesthetics

Wire-Brushed

A rotary wire brush removes soft grain fibers and surface debris, leaving the harder growth rings raised and deeply textured. Reveals the grain structure without removing the aged character.

Best For

Mantels, decorative beams where tactile quality matters

Smooth-Planed

All four faces are planed smooth, revealing the fresh wood beneath the weathered surface. Clean, contemporary appearance while maintaining the old-growth density and grain pattern.

Best For

Modern interiors, minimalist design, beams where a clean surface is desired

Sandblasted

High-pressure media blasting removes soft wood fibers more aggressively than wire brushing, creating an extremely textured surface with deep grain relief. Dramatic visual and tactile effect.

Best For

Statement installations, commercial feature beams, rustic-industrial aesthetics

Charred (Shou Sugi Ban)

Surface charring with a propane torch creates a blackened, alligator-skin texture. After brushing off the loose char, the beam has a dramatic blackened surface with enhanced weather resistance.

Best For

Contemporary design, exterior applications, Japanese-inspired interiors

Application Guide

Structural vs. Decorative Beams

Structural Use

Load-Bearing Beams

For structural applications, a beam has to be assessed for the job. Inspect it for deep checking, rot, insect damage, and cross-grain defects, and bring in a licensed engineer early.

  • Have a licensed engineer assess the beam and the span
  • Check current regulations with your local building official
  • Ask whether a stamped review is needed for your permit
  • Ask suppliers what is known about the source of the beam
  • Choose species to suit the load
  • Check moisture content before installation
  • Treat span tables as preliminary sizing only
Decorative Use

Feature & Accent Beams

Decorative beams are chosen for visual character: deep patina, weathering, tool marks, nail holes, and grain patterns. Solid beams or hollow wraps can both work, and hollow wraps reduce weight.

  • Hand-hewn beams with strong character marks
  • Hollow beam wraps for non-structural ceiling applications
  • Finishes such as wire-brushed, sandblasted, oiled, or waxed
  • Mantel beams cut and finished to length
  • Box beams made from reclaimed planks
  • Steel beam wraps to conceal modern structural elements
  • Stain and color matching by a finisher
Fireplace Feature

Reclaimed Beam Mantels

A reclaimed beam mantel is a simple way to change a room. The weight and texture of an old timber can turn a fireplace from a functional feature into the visual anchor of the space.

Include the length and finish you want in your request, and ask partner suppliers what is available. Some suppliers can cut a beam to length, and photos help you choose.

Common Mantel Sizes

Length48" to 84"
Depth (front to wall)6" to 10"
Height (visible face)4" to 8"
Weight30-120 lbs depending on size and species

Mantel Installation Methods

Concealed Bracket Method

Steel L-brackets or floating shelf brackets are lag-bolted to wall studs. The mantel slides over the brackets and is secured with set screws from below. No visible hardware.

Rebar/Rod Method

Steel rods (typically 1/2" rebar) are epoxied into wall studs and corresponding holes in the beam. The beam slides onto the rods for a completely invisible mount. Best for heavy mantels.

Corbel/Bracket Method

Decorative brackets or corbels (reclaimed iron or carved wood) support the mantel from below. The hardware becomes a design element. Period-correct for historic homes.

Clearance Requirements

Wood mantels need clearance from the fireplace opening, and the required distance depends on how far the mantel projects. Check the fireplace manufacturer's instructions and current regulations with your local building official.

Connection Details

Connection Hardware & Fasteners

How you connect a beam to the supporting structure is as important as the beam itself. Here are the most common connection methods. Have an engineer specify connections for structural work.

Concealed Steel Brackets

Heavy-gauge steel brackets that mount to the wall structure and are hidden inside a slot cut into the beam end. The beam appears to float from the wall with no visible hardware.

Best ForDecorative ceiling beams, mantels, floating beam installations

Through-Bolts with Washers

Galvanized or stainless steel bolts that pass completely through the beam and the supporting structure. Exposed bolt heads and washers become a design element in industrial and rustic settings.

Best ForStructural connections, industrial aesthetics, timber-frame joinery

Lag Screws (Structural)

Heavy-duty lag screws driven into supporting structure through the beam. Heads can be countersunk and plugged for a cleaner appearance. Capacity varies by size, species, and embedment.

Best ForBeam-to-post connections, header installations, supplemental fastening

Engineered Metal Connectors

Metal connectors made for timber connections, such as beam hangers, post caps, and column bases, with load ratings published by the manufacturer.

Best ForStructural connections, post-and-beam framing, deck construction

Traditional Timber Frame Joinery

Mortise-and-tenon joints, dovetails, and pegged connections that require no metal hardware. The same methods used to build many of the structures these beams came from.

Best ForTimber-frame construction, visible joinery as a design feature, historic restorations
Planning Your Installation

Installation Considerations

Installing a reclaimed beam — especially a heavy one — requires careful planning around weight, access, rigging, and structural support.

Weight Planning

A 12x12 oak beam 16 feet long weighs well over 600 lbs. Work out total weight from the per-foot figures in the weight table, then plan your rigging and lifting strategy. Interior installations may require removing windows or doors for access.

Structural Support Assessment

Before installation, verify that the receiving structure can support the beam weight plus any applied loads. Ceiling joists, wall studs, and posts must be evaluated by a qualified professional.

Access and Rigging

For heavy beams, professional rigging is recommended. A telehandler, crane, or engine hoist may be needed for exterior lifting. Interior beams may require scaffolding, temporary supports, and several helpers.

Finishing Before Installation

Apply any surface treatments (oil, wax, sealer) before installation. It is much easier to finish a beam on sawhorses than 10 feet overhead. Touch up any installation damage after the beam is in place.

Expansion and Movement

Large timbers can expand and contract seasonally. Allow 1/4 inch clearance at beam ends when fitting into pockets or against walls. Use flexible caulk or trim to conceal the gap if needed.

For Structural Use

Working With a Structural Engineer

For structural beam applications, hire a licensed structural engineer. Here is the kind of work an engineer typically does on a reclaimed timber project.

Beam Assessment

An engineer or qualified grader can examine a beam and assign design values based on species, size, and condition.

Load & Span Calculations

Structural analysis covers dead load, live load, and deflection, to determine whether a specific beam can safely span the required distance.

Connection Design

Connection details specify hardware, fastener sizes, and bearing area, so the connections are suited to the loads on the beam.

Site Review

On complex installations, an engineer may visit the site to verify conditions and review connections.

Common Questions

Beam FAQ

How do I get a heavy beam into my house and up to the ceiling?

Plan the lift before the beam arrives. Heavy beams may need a crane, telehandler, or engine hoist, and a rigging crew experienced with timber installation. Lighter beams and mantels can often be managed by two strong people with the right scaffolding.

Will my ceiling support the weight of a reclaimed beam?

This is an engineering question that depends on your ceiling structure, span, and the weight of the beam. Decorative beams can often be supported by ceiling joists if properly blocked and lagged. Heavier beams may need support posts or additional framing. Consult a structural engineer before installation.

Can I use a reclaimed beam as a structural element in new construction?

Possibly, but plan on engineering review. A licensed structural engineer can assess a reclaimed beam based on species, size, and condition. Check current regulations with your local building official before you commit to a beam.

What is the difference between a solid beam and a box beam?

A solid beam is a single piece of timber, heavy and suitable for structural or decorative use. A box beam is hollow, made from reclaimed planks around an internal frame. Box beams are far lighter and easier to install overhead, but they do not carry structural loads.

Do reclaimed beams have checking (cracks)?

Yes, surface checking is normal in large timbers. It occurs when the exterior dries faster than the interior, causing cracks along the grain. Checks are usually cosmetic and are often valued in exposed beams, but deep splits in a structural beam need assessment.

Can beams from different sources be matched so they look similar?

Matching species, age, surface texture, and color tone is easiest when beams come from the same source. For projects with multiple beams, ask partner suppliers what is available and request photos. Wire-brushing or sandblasting all beams to the same finish also helps create visual consistency.

How do I maintain an exposed beam after installation?

Interior beams need very little maintenance. A light dusting once or twice a year is usually enough. If you applied a penetrating oil or wax finish, reapply every few years to maintain the sheen. Exterior beams should be sealed with a penetrating wood preservative and recoated every few years, depending on sun and weather exposure.

Environmental Benefits

Reusing a Beam Avoids Cutting and Milling a New One

Large timbers come from large trees that take a long time to grow. Putting an existing beam back to work makes use of wood that has already been cut.
