Features

Material

Steel:

S250GD + ZPRO

Corrosion protection:

ZPRO coating - corresponding to a zinc layer of approx. 55 μm

Advantages

  • Light and easy to handle
  • No pre-drilling required
  • Reduced environmental impact due to material reduction
  • Flexible fastening options
  •  

Features

​Built to last, the surface of the PBWS is protected using our ZPRO coating for improved resistance to corrosion compared with conventionally coated galvanised steel. This makes the PBWS a good choice for a wide variety of outdoor projects including pergolas, decking, car ports, fencing and sheds.

Optional hole patterns mean it can be fastened to the timber post using either 4 x CSA connector screws or 2 x SSH Hex Head screws, no pre-drilling is required.

Reduced Environmental Impact

PBWS offers the same load-rated capacity as standard post bases, yet due to it's unique folded build, requires up to half as much steel material to produce, making it better for the environment and easier to handle.
