Finishes & corrosion protection

Zinc plated: economical interior finish with moderate corrosion resistance.
Ruspert/ceramic coatings: improved salt spray performance for exterior cladding.
Stainless steel: essential for coastal cities and wet zones to avoid staining and callbacks.

Compliance & documentation

Consultants increasingly request mill test certificates and salt spray reports. MOJAF provides EN and ASTM references, as well as factory certificates on request. Keep batch numbers noted on delivery notes for traceability.

Stock planning & delivery

Core SKUs are held in Riyadh, Jeddah and Dammam for 24–48 hour dispatch.
Bulk orders can be palletised by site zone and labelled for phased installation.
Include matching anchors, washers and threaded rods to avoid shortages on site.

Pair screws with flooring & skirting packages

When supplying vinyl or SPC flooring, specify screws for trims, stair nosings and transition profiles to maintain warranty requirements. Coordinate with wall and floor skirting deliveries so installers receive a complete kit.
