Steel profile

U-shapedspecialconstruction

Overview
Cold roll-formed steel profiles designed for volumetric modular buildings provide complex cross-sections, increased stiffness and precise length and hole tolerances that improve repeatability and assembly speed for modular units.

Key messages
Cold roll-forming and integrated downstream processing allow production of single-profile solutions with enhanced functionality, tighter tolerances and plug-&-play features that accelerate module assembly and installation.

Benefits

• Thicker sections and higher-strength steel grades — greater structural capacity and more internal space for a given external module footprint.
• Complex, multi-feature profiles — reduce component count and simplify assembly by combining functions into a single profile.
• Tighter length and positional tolerances — consistent, repeatable fit across full module lengths to minimize rework.
• Downstream processing (laser, welding, bending, pre-stress) — delivered components ready for faster, simpler on-site assembly.

Characteristics / technical specifications

• Cold roll forming enables complex steel profile geometries with higher stiffness compared to hot-rolled alternatives.
• Capability to cold roll-form steel profiles up to 8 mm thickness (exceeding typical 4–5 mm limits).
• Use of higher-strength steel grades for reduced footprint with increased structural capacity.
• Maintenance of critical length tolerances over full module lengths; reduction of common roll-forming end defects such as end splay and end-cut straightness issues.
• Extremely accurate hole positioning along the profile length with tight control over tolerance stacking for consistent component fit.
• Extensive downstream capabilities including 5-axis laser processing, robotic welding, profile bending and pre-stressing to ensure fit and facilitate assembly.
• Profiles intended for ceiling beams, roof beams, floor beams, corner posts, corner supports and similar structural module components.
