We manufacture all of our Stoneguards locally here in Christchurch.  We carry stock of many makes and models. 

Each Stoneguard is acid cleaned and etched before being powder coated locally to a very high standard. 
Satin Black is the most popular powder colour coated Stoneguard .
After powder coating we do a final quality control check before it is packaged.

We can courier the stoneguard to you, or we offer a full installation service on site in Hornby, Christchurch.
