How close to coastal areas can you use Boxspan?

Spantec uses Bluescope ZINC HI-TEN G550 Z450 steel to manufacture Boxspan. This is the highest coating as standard on the market.

Z450 is suitable up to C4- Atmospheric Environments per the NCC and NASH codes.

We supply SHS as standard in ZB135/135 and can provide additional HDG to AS/NZS 4680 so all Spantec components can comply up to C4.
