Galvanised Roller Shutter Doors in Midrand

Galvanising is a specification decision rather than a product category, and it is what most often determines whether a Midrand door lasts eight years or eighteen. The zinc coating protects steel where paint alone fails.

Where galvanised roller shutter doors are worth it in Midrand

• External openings taking Highveld summer storms and standing water at the threshold.
• Wash-down areas and food handling behind the restaurants and food retail at Waterfall.
• Plant rooms and generator enclosures, where heat and fumes work on unprotected steel.
• Basement openings with poor ventilation and constant condensation.
• Works and yards at Olifantsfontein and Clayville where dust and chemicals are in the air.

Galvanised and powder coated roller shutter doors

For most Midrand commercial work we supply galvanised curtains powder coated to the building or tenant colour, which gives corrosion protection underneath and the appearance the landlord wants on top. Where appearance is irrelevant, self-colour galvanised is cheaper and entirely appropriate.

Corrosion detail on galvanised roller shutter doors

Corrosion almost never starts mid-slat. It starts at cut edges, fixings, the bottom rail where water sits, and inside guides that never dry out. We treat those as part of the specification and choose fixings that will not react against the coating.

When a galvanised roller shutter door is not necessary

An internal, dry, sheltered opening in an office building does not need galvanising and we will say so. Selling a corrosion specification into a corridor inflates a quotation and does nothing for you.

Maintaining galvanised roller shutter doors

Galvanised doors still need servicing. Guides need cleaning so water and grit do not sit in them, and coating damage from vehicle contact should be made good before it starts working.
