We recommend all glulam members receive a factory coat of penetrating stain or clear sealer. Please ask for samples of our standard stains.
Typically a smooth, factory planed finish with eased corners is provided for all members. Other textures are available, which simulate rough sawn lumber, hewn timber, etc.
Penetrating end sealer is factory applied to all cross-grain cuts in the factory.
Coatings which affect flame spread values of glulam are available. However, we recommend they be field applied because surface marring during handling can occur with these coatings.
Design values are available in ANSI 117-2010, which can be downloaded free here.
24F-V3 for simple span beams
24F-V5 for continuous span beams
#47/1:8 or #49/1:10 for columns or other members not loaded primarily in strong axis bending
We design and fabricate custom steel connections and hardware for almost all of our projects. Contract documents can show fully detailed connections or specify whether factory designed connections should be fully concealed, partially concealed (bolts visible but plates concealed,) or fully visible.
Our default steel finish is galvanized hardware (bolts, nuts, shear plates, etc.) and gray primer on steel plates and shapes. Other options include: All galvanized, all powder coated, and stainless steel.
Typically steel shapes and plates are A36, and bolts are A307.
