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 19th-century timber framing. Each beam is genuinely one-of-a-kind.

Key Characteristics

  • Visible axe marks and adze texture
  • Irregular cross-sections add visual depth
  • Typically oak, white pine, or hemlock
  • Ages range from 80 to 180 years

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
  • Ages range from 60 to 120 years

Best For

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

Box Beams

Hollow beams fabricated from reclaimed planks, built around a lightweight internal frame. Provide the visual impact of a solid timber at a fraction of the weight. Ideal for ceiling applications where structural support is not needed.

Key Characteristics

  • Fabricated from authentic reclaimed planks
  • Fraction of the weight of solid beams
  • Custom sizes — any width, depth, or length
  • 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

Lightweight Alternative

Beam Wrap & Faux Beam Construction

Box beams deliver the visual impact of a solid timber at a fraction of the weight. Built from authentic reclaimed boards around a lightweight internal frame, they are indistinguishable from solid beams once installed — and dramatically 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 precision-mitered and joined around an internal lightweight frame (typically 2x4 or 2x2 furring). Three-sided for ceiling-mount applications, four-sided for free-standing or wrapping existing structural members.

Wall Thickness

3/4 inch for most residential applications, 1 inch for wider beams (10 inch+ face), and 1-1/2 inch for commercial installations requiring maximum visual weight and durability.

Weight Comparison

A box beam weighs 70-80% less than a solid beam of the same exterior dimensions. An 8x8x12ft solid oak beam weighs 230 lbs; the same size box beam weighs approximately 45-60 lbs.

Maximum Size

Box beams can be fabricated to virtually any dimension — 6 inch to 24 inch face width, 4 inch to 18 inch depth, any length up to the maximum board length available (typically 16-20ft).

Installation Advantage

Lightweight box beams can be installed by two people with basic scaffolding. No crane, telehandler, or specialized rigging equipment required.

Steel Beam Wraps

We custom-fabricate box beams to wrap existing steel I-beams, LVLs, or glulam beams. The reclaimed wood shell conceals the modern structural element while providing authentic timber appearance.

Surface Treatments

Surface Finish Options

The surface treatment you choose defines the visual character of your beam. From raw patina to smooth-planed contemporary, we offer six standard surface options.

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, we preserve the original axe marks and adze facets while cleaning the surface 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, high-end residential

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, we select beams that meet or exceed modern engineering requirements. Every structural beam is inspected for checking, rot, insect damage, and cross-grain defects.

  • Graded to meet local building code requirements
  • Engineer-stamped when required by your municipality
  • Load calculations provided upon request
  • Full provenance documentation for insurance purposes
  • Species selection matched to load requirements
  • Moisture content verified (target 12-15% for structural)
  • Span tables referenced for preliminary sizing

Decorative beams are selected for visual character — deep patina, weathering, tool marks, nail holes, and grain patterns. We can supply full-solid beams or hollow beam wraps to reduce weight.

  • Hand-hewn beams with maximum character marks
  • Hollow beam wraps for non-structural ceiling applications
  • Custom finishing: wire-brushed, sandblasted, oiled, or waxed
  • Mantel-ready beams cut and finished to your specifications
  • Box beams fabricated from reclaimed planks
  • Steel beam wraps to conceal modern structural elements
  • Custom staining and color matching available
Fireplace Feature

Reclaimed Beam Mantels

A reclaimed beam mantel is one of the single most impactful design elements you can add to a room. The weight, texture, and history of a 100-year-old timber transforms a fireplace from a functional feature into the visual anchor of the entire space.

We prepare mantel beams to your exact specifications — cut to length, finished on all visible faces, and ready for installation. Many customers visit our yard to hand-select their mantel from our current inventory.

Standard Mantel Sizes

Length48" to 84" (custom lengths available)
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

Building codes typically require a minimum of 6 inches of clearance between the top of the fireplace opening and the bottom of a combustible mantel, plus 1 inch of additional clearance for every 1/8 inch the mantel projects beyond the fireplace face. Check with your local code authority for exact requirements.

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 we use and recommend.

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.

Load RatingUp to 2,000 lbs per bracket (varies by model)
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.

Load RatingUp to 5,000+ lbs per bolt (varies by diameter)
Best ForStructural connections, industrial aesthetics, timber-frame joinery

Lag Screws (Structural)

Heavy-duty lag screws (typically 1/2" diameter, 6-12" length) driven into supporting structure through the beam. Heads can be countersunk and plugged for a cleaner appearance.

Load RatingUp to 1,200 lbs per screw in solid wood (varies by species and embedment)
Best ForBeam-to-post connections, header installations, supplemental structural fastening

Simpson Strong-Tie Connectors

Engineered metal connectors specifically designed for timber connections. Beam hangers, post caps, and column bases that meet building code requirements with published load ratings.

Load RatingPublished by manufacturer — varies by connector model
Best ForCode-required structural connections, post-and-beam framing, deck construction

Traditional Timber Frame Joinery

Mortise-and-tenon joints, dovetails, and pegged connections that require no metal hardware. Authentic to the original building methods used to construct the buildings these beams came from.

Load RatingVaries — requires engineering analysis for structural applications
Best ForAuthentic timber-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 12x12x16 foot oak beam weighs over 640 lbs. Calculate total weight using the per-foot figures in our size table, then plan your rigging and lifting strategy accordingly. 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 for structural adequacy.

Access and Rigging

For beams over 200 lbs, professional rigging is recommended. A telehandler, crane, or engine hoist may be needed for exterior lifting. Interior beams may require scaffolding, temporary supports, and multiple crew members.

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.

Common Questions

Beam FAQ

How do I get a 500-pound beam into my house and up to the ceiling?

For heavy beams, we recommend hiring a rigging crew experienced with timber installation. Beams over 300 lbs typically require a crane, telehandler, or engine hoist to lift into position. We can recommend experienced installers in the Twin Cities who specialize in reclaimed beam placement. For lighter beams and mantels under 150 lbs, two strong people with the right scaffolding can usually manage.

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. For heavier beams, you may need to add support posts, sister additional joists, or install a steel plate above the ceiling to distribute the load. We strongly recommend consulting a structural engineer before installation.

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

Yes, but it requires engineering approval. A licensed structural engineer can visually grade a reclaimed beam, calculate its allowable loads based on species, size, and condition, and provide a stamped approval that satisfies building code requirements. We work with several engineers in the Twin Cities who specialize in reclaimed timber structures.

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

A solid beam is a single piece of timber — heavy, authentic, and suitable for both structural and decorative use. A box beam is hollow, fabricated from reclaimed planks nailed or glued around an internal frame. Box beams weigh 70-80% less than solid beams and are much easier to install overhead, but they cannot carry structural loads.

Do reclaimed beams have checking (cracks)?

Yes, surface checking is normal and expected in large reclaimed timbers. Checking occurs when the exterior dries faster than the interior, causing surface cracks along the grain. These checks are cosmetic only and do not compromise structural integrity. Checking is considered a desirable character feature in exposed beam applications. Deep splits that affect structural capacity are flagged during our grading process.

Can you match beams from different sources so they look similar?

We do our best to pull beams from the same salvage source or at minimum match species, age, surface texture, and color tone. For projects requiring multiple beams, we recommend visiting our yard to hand-select from our current inventory. Wire-brushing or sandblasting all beams to the same finish level also helps create visual consistency.

How do I maintain an exposed beam after installation?

Interior beams require very little maintenance. A light dusting once or twice a year is sufficient. If you applied a penetrating oil or wax finish, reapply every 3-5 years to maintain the sheen. Exterior beams should be sealed with a penetrating wood preservative and recoated every 2-3 years depending on sun and weather exposure.

Eco Impact

A Single Reclaimed Beam Saves an Entire Mature Tree

Large-dimension timbers require old-growth trees that take 60 to 100 years to reach harvestable size. Every reclaimed beam we sell represents a tree that stays in the forest — continuing to sequester carbon, filter air, and support biodiversity.
