Economical, highly rigid structural steel portal frame systems featuring engineered moment-resisting haunch connections for wide-span industrial halls.
Precision manufacturing parameters, steel grades, connection hardware, and performance metrics.
How vertical gravity, lateral wind, and seismic forces are dissipated through our engineered framing.
Roof dead and snow loads are transferred through cold-formed Z/C purlins onto hot-rolled IPE/HEA structural steel portal rafters. Bending moments are maximum at the eaves and ridge, where engineered bolted haunches provide expanded internal lever arms (z), drastically reducing rafter steel weight while maintaining structural stiffness.
Wind suction, pressure, and seismic inertia are resisted through rigid moment-resisting knee joints and longitudinal roof/wall cross-bracings. Column baseplates are designed as pinned or semi-rigid connections with high-tensile anchor bolts absorbing shear and axial foundation reactions per Eurocode 3.
Fully compatible with high-performance PIR sandwich panels (40mm–150mm) or non-combustible mineral wool panels achieving U-values down to 0.14 W/m²K. Structural members are protected with intumescent fire coatings (R30, R60, R90) or hot-dip galvanizing per ISO 1461.
Fully verified structural calculations meeting European, British, and international building codes.
Second-order (P-Δ) global analysis and member stability verification for IPE/HEA columns.
Component method verification of bolted end-plate moment connections under peak MEd.
Internal and external pressure coefficients (cpe, cpi) for low-pitch portal roofs.
Full non-destructive testing (NDT), certified robotic welding, and CE marking.
From 3D Tekla BIM modeling to automated roll-forming, container packing, and on-site bolted erection.
Full second-order frame analysis and parametric connection design with CNC machine export.
CNC robotic beam line cutting, drilling, and plasma haunch fabrication with SA 2.5 shot-blasting.
Rafters segmented with bolted splice joints to fit perfectly inside standard 40ft High Cube containers.
On-site crane erection using calibrated Grade 8.8/10.9 bolts—zero hot welding required on site.
Why civil engineers, architects, and international contractors specify this SerBuild technology.

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.
