Metal construction in Morocco

A steel building is not just its frame. Between the portal frame and the finished building there is the envelope, the floors, the access and the metalwork — packages that, split between contractors, create interfaces and delays.

We handle the lot, from design to erection.

What we supply

• Steel structures — primary and secondary framing, strengthening
• Cladding — profiled sheeting, composite panel, double skin
• Roofing — profiled sheet, insulated panel, rooflights
• Floors — joists, chequer plate, composite decking
• Staircases and walkways — access platforms, maintenance gantries
• Handrails and metalwork — edge protection, doors, frames
• Modular units — plant rooms, site offices

Envelope: what drives the choice

Our process

1. Survey and brief — area, height, use, operating constraints; site survey where there is an existing building
2. Engineering — load take-off, RPS 2011 seismic check, envelope selection
3. Drawings — frame, cladding and roofing setting out, junction details
4. Workshop fabrication — cutting, drilling, assembly, welding
5. Protective treatment — hot dip galvanising or paint system according to exposure
6. Frame erection — lifting, bolting, alignment
7. Envelope — cladding, roofing, flashings
8. Finishes — metalwork, handrails, doors, handover

Junction details: where leaks start

On a steel building, defects almost never appear in the middle of a sheet. They appear at the junctions: ridge, verge, flashings, roof penetrations, cladding to roofing transitions, cladding feet.

These details need proper accessories and setting out anticipated at design stage, not improvised on site. That is the difference between an envelope that lasts ten years and one that leaks in the first winter.

Floors

Two families. Joists with decking — IPE or UPN joists and chequer plate — are demountable and quick, suited to plant platforms and storage mezzanines. Composite floors combine profiled steel deck with an in-situ concrete slab: heavier, but better stiffness, better fire performance and better acoustics.

For storage buildings specifically, our steel warehouse page sets out the spans, clear heights and the seven factors that actually drive the price.
