Image showing arrangement of two C-Sections on the corner of the building envelopeHayes Cladding's range of C-Sections provide useful structural solutions to an array of construction and industrial applications, e.g. Mezzanine Floor beams, cladding rails, structural support members (gable rafters and columns), window and door trimmers, brickworks restraints and wind bracing.

These cold formed structural channel sections are manufactured from high tensile Z39 steel, are pre-galvanised so no additional finish is required and satisfy the requirements of BS5950: Part 5 (1998). Their high strength to weight ratio enable practical substitution for hot rolled steel sections whilst easing installation and site handling.


  • Pre-Galvanised - no additional finishing or painting required

  • Pre-punched holes -minimising assembly time and errors

  • Wide range of sections, gauges and spans to suit an array of applications


  • Side rails -  Our C-sections are compatible with the Z-purlin range and can be used as a substitute.

  • Mezzanine floors - C-sections can be used either as primary or secondary floor beams in mezzanine floors.

  • Parapet posts - used in a 'back to back' formation, C-sections provide a cost effective alternative to hot rolled sections in a parapet situation.

  • Brick work restraints - as an alternative to hot rolled sections, C-sections used to restrain brick work offer benefits of significant cost savings, light weight on-site handling and no additional finishing.

  • Door posts / windows - C-sections can also be utilised for framing doors and windows. Due to the fact that the sections are the same size as Z-purlins, alignment on-site can be achieved with minimal effort.


The diagrams below refer to all C-section sizes (C-140, C-170, C-200 and C-240). The dimensions for a specific C-section can be referenced in the table below. Click here to download CAD drawings for any of our products.

Fixing DetailsDiagram showing relation of C-sections to cleat

Side rail butted system

The butted system offers a simple cleat connection (the cleat is welded or bolted to the hot rolled steel section) where two butted C-sections are fastened directly to the cleat. This is suitable for smaller buildings, short or uneven span or light loading applications. Image showing C-sections fixed in a butted arrangement to a vertical steel beam

This system can also cater for single bay situations, therefore can be used in conjunction with other cladding support systems. Spans of up to 8m can be accommodated, depending on the loads involved, where the cladding or the liner tray offers the correct lateral support by the way it has been fixed.



Side rail sleeved system Diagram showing relation of C-sections to sleeve

This system is primarily for spanning over two or more bays. The sleeved system incorporates a cold rolled sleeve to which two C-sections are bolted to the cleat. For technical advise, contact our sales department.
