Timber Framing & Wood Structures

Timber framing construction with wooden beams and fastener connections for residential building projects

TUHU Fasteners offers a full range of heavy-duty fasteners for timber beams, engineered wood framing, and mass timber assemblies used in both commercial and residential structures.

We manufacture timber bolts, carriage bolts, square head bolts, hex bolts, hex lag screws, and timber screws—engineered for joists, trusses, and heavy timber framing applications.

Finishes include hot-dip galvanizing (HDG) for outdoor framing, black oxide or plain finish for interior use, and zinc plating for cost-effective corrosion protection.

Supported Standards:

✔ ASTM A307, A153, A123
✔ ISO 898-1, ISO 3506 (for stainless)
✔ EN 15048
✔ BS 7419
✔ DIN 601 / DIN 603 (for square & carriage bolts)

Material & Finish Options for Timber Framing & Wood Structures

Fasteners for timber framing and wood structures are typically made from carbon steel for strength and affordability. For outdoor applications or treated wood, stainless steel may be used to prevent long-term corrosion.

Hot-Dip Galvanized (HDG) finishes are widely applied for weather-exposed framing, ensuring resistance to moisture and rot-inducing conditions. For indoor or covered framing, zinc plating and plain black oxide finishes are common, balancing protection and cost.

At TUHU, we provide fastener finishes tailored for timber beams, joists, trusses, and both residential and industrial wood framing systems.
