This 310mm wide coping is designed for walls measuring between 200mm and 250mm in thickness.
Aluminium is naturally corrosion-resistant, and the protective finish further ensures it will not rust like traditional steel products.
No, this specific product is engineered for 90-degree angles only. Attempting to force it into another angle will compromise the structural integrity and weatherproofing.
Typically, fixings should be sourced separately based on the specific substrate of your wall to ensure a secure attachment.
Occasional cleaning with mild soap and water is sufficient. Avoid using pressure washers directly on joints or seals.
Ensure the underlying wall structure is perfectly level and use high-quality architectural sealant at all connection points.
Clean the surface with a non-abrasive cloth and mild detergent; avoid harsh chemicals or abrasive sponges.
For optimal setup, ensure the parapet wall is level and clear of debris before installation. The 310mm width is specifically compatible with walls between 200mm and 250mm; check your wall width precisely before procurement. Use appropriate fasteners recommended for aluminium to avoid galvanic corrosion. Care for the product is minimal: periodic inspection of the joints for any sealant degradation is advised, and a simple wash with mild soapy water once or twice a year will keep the black finish looking new and free from heavy grime buildup.
