Due to the recent Covid-19 outbreak, our trade counter is no longer open for customers.

All future orders will be delivery only, but due to demand, there may be some delays.

We have made arrangements with suppliers to send items direct on a next day service on items that have a 3 day availability and are not on our shelves. These charges are set by our manufacturers and will depend on items ordered and delivery postcode, but should help with clearing backlogs and ensuring deliveries are received quickly if required.

This information may change at any time.

Galvanised coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Galvanise is a coating that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity.
