TimberShield V-leg timber canopy at dusk — two Douglas Fir V-legs with glass roof illuminated at sunset on golf course
Structural Engineering

Engineered to last 30–50 years.

IBC compliant. Permit-ready. Built for Pacific Northwest snow loads and year-round all-weather use.

📋
IBC Engineered

Every TimberShield structure is designed to International Building Code standards. Stamped structural drawings available for permit submission.

❄️
Snow Load Rated

Designed for 25–80 PSF ground snow load depending on your location. We specify the correct loading during the quote process.

💨
Wind Rated

Engineered for 110–150 MPH wind exposure. V-leg geometry distributes lateral wind loads across two anchor points — more stable than single-post systems.

🏛️
WEBS Registered

Pre-qualified on Washington State's WEBS procurement system. MRSC roster ready for transit and municipal project procurement.

Materials

What it's made of.

01

Douglas Fir — #1 Structural

10×14 timbers — legs, cap beam, cross beams

Premium #1 structural grade Douglas Fir — the strongest, most dimensionally stable species in the Pacific Northwest. Sustainably harvested, renewable, and far warmer than steel or aluminum. Oil-finished for long-term UV and moisture resistance.

Fb: 1,500 psi E: 1,800,000 psi Density: 35 pcf
Sourced from Washington Timber Co. →
02

Fabricated Steel Base Plates

Custom welded — per V-leg assembly

Each base plate is custom fabricated for the V-leg geometry — two timber pockets at 11° each, anchor bolt pattern specific to the footing design. Hot-dip galvanized or powder-coated black standard.

03

Concrete Footings

Typically 24" dia. × 36" deep with rebar cage

Footings are designed per structural engineer's specification for your soil type and local frost depth. We handle the footing pour as part of installation — you get a turnkey system.

04

Laminated Glass Roof

¼″ or 9/16″ laminated tempered glass

Two glass specifications available. ¼″ lam glass panels with aluminum rails for standard applications. 9/16″ laminated tempered for higher load requirements or commercial applications.

05

Standing Seam Metal Roof

26-gauge Galvalume steel panels

Pre-painted 26-gauge Galvalume standing seam. Maximum durability and lowest maintenance. Available in a range of colors to match your existing structures.

06

Steel Hangers & Hardware

Simpson Strong-Tie and custom fabricated

All structural connections use Simpson Strong-Tie hardware or custom fabricated steel angles — specified per load requirement. No visible hardware on public-facing faces.

Permitting

Getting your permit approved.

Most jurisdictions require a building permit for any permanent anchored structure. TimberShield provides a complete permitting documentation package with every installation:

  • Stamped structural drawings (architect or engineer of record)
  • Site-specific load calculations (snow, wind, seismic)
  • Concrete footing design with rebar specification
  • Hardware and connection schedule
  • Material specifications and grades
  • Response to building department comments

We have successfully permitted structures in Washington, Oregon, California, and Arizona. The permit process typically takes 3–6 weeks.

Need stamped drawings?

We can provide structural drawings for preliminary permit review before you commit to a full installation. Contact Shawn to discuss.
