High-precision structural cold-formed steel sections roll-formed to tight EN 10162 tolerances with automated CNC dimpling, swaging, and service hole punching.
Precision manufacturing parameters, steel grades, connection hardware, and performance metrics.
How vertical gravity, lateral wind, and seismic forces are dissipated through our engineered framing.
Structural C, U, Z, and Sigma profiles (depths 75mm to 350mm, gauge 0.75mm to 3.50mm) act as primary framing, floor joists, wall studs, roof purlins, and wall girts. Roll-formed from high-yield S350GD/S450GD steel, their return lips and longitudinal stiffening ribs increase section modulus (Weff) by up to 40% over plain channels.
Z and Sigma purlins feature asymmetrical flanges allowing continuous overlapped lap joints over portal rafters, creating continuous multi-span beam action that reduces mid-span bending moments and deflections under storm winds.
Continuous hot-dip galvanizing with Z275 (275 g/m²) or Z350 (350 g/m²) zinc mass provides self-healing cathodic protection at all cut edges and punched holes per EN 10346.
Fully verified structural calculations meeting European, British, and international building codes.
Effective width calculations accounting for local buckling and distortional buckling.
Strict dimensional, angular, and straightness tolerances for cold roll-formed sections.
Continuous hot-dip coated steel flat products technical delivery conditions.
Mill test certificates verifying yield strength, elongation, and chemical analysis.
From 3D Tekla BIM modeling to automated roll-forming, container packing, and on-site bolted erection.
Direct transfer of hole coordinates, swaging zones, and cut lengths to roll-formers.
Cold-forming through progressive precision tooling stations without micro-fracturing.
Nested profile packing saving up to 60% container space with steel edge protectors.
Lap purlins connected with Grade 8.8 bolts or self-drilling structural fasteners.

Detailed answers to technical, manufacturing, export, and on-site assembly questions.
SerBuild designs and manufactures light gauge steel (LGSF) and heavy structural steel buildings for residential developments, industrial warehouses, manufacturing factories, aircraft hangars, commercial offices, and agricultural halls.
Yes. All structural engineering is performed strictly according to Eurocodes (EN 1990, EN 1991, EN 1993, EN 1998) including project-specific National Annex parameters for local snow, wind, and seismic loads.
We offer five flexible delivery packages: Engineering Only, Supply Only (containerized flat-pack kit), Supply with On-Site Supervision, Complete Frame Installation, and Turnkey Project Delivery in eligible regions.
Components are precision roll-formed or cut, permanent piece-marked, and packed in dense weather-protected flat-pack bundles optimized for 40ft High Cube containers, accompanied by detailed 3D packing lists and assembly manuals.
