Please note: The length of hooks required equals lap + 2-3mm. Having determined exposure to prevailing weather conditions and taking into account adverse local effects, use the info below to establish head lap:

• Only the 316 grade can be guaranteed in industrial areas or severe coastal exposure (front of sea).
• The coating is purely decorative and does not influence the resistance to corrosion of the material.
• The coating will usually last ten years or more, except in very abrasive conditions (salted winds for instance).
• Hooks are often used when making small repairs or replacing individual slates on the roof.
