3. Timber Steel Manufacturing Process (With Visual Flowchart)

Material Selection: Premium graded timber (FSC certified) and high-strength rolled steel (Q235/Q345/SS400/EN S355 or specified grade) are selected.
(ISO 9001-compliant sourcing)

→

Precision Cutting: Timber is CNC or laser-cut (±0.2mm tolerance); steel is plasma/water-jet cut per 2D/3D models.

→

Mating & Joint Design: Steel and timber members are aligned; joints/brackets (e.g., steel timber brackets, timber frame steel brackets) are fabricated with interlocking slots and mechanical fasteners (ISO 898, DIN EN 1090 tested).

Surface Treatment: Steel undergoes hot-dip galvanization, powder-coating, or epoxy painting (200–350μm), achieving >750 hours salt fog test resistance. Timber is pressure-treated for fire and bio-resistance.

→

Assembly/Quality Testing: Integrated assemblies are torque and load tested (EN1090, ANSI/AISC standards). Nondestructive testing (NDT) is performed on welds, corrosion, and geometric fit-up.

→

Logistics/Delivery: Certified timber steel assemblies are packed, serialized and prepared for site delivery. Digital product passports support traceability.
