Frequently asked
Which throughbolt range do I need?
Match the finish to the environment - zinc plated for dry internal work, hot dip galvanised outside, A2 or A4 stainless for coastal and marine - then check whether the specification calls for a European Technical Assessment: Option 1 covers cracked and non-cracked concrete, Option 7 non-cracked only. If in doubt, send us the fixing schedule and we will match the range.
