PBWS Folded postbase
PBWS is single-piece, non-welded post base for connecting timber to concrete. An engineered solution, this connector requires up to 45% less steel than a traditionally designed post base.
Product Details
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.
Extend the life of outdoor structures
Our innovative ZPRO coating provides additional corrosion resistance for structural steel connections typically used in outdoor settings such as car ports and gardens.
It provides the same protection against the elements as a hot dip galvanised coating (corrosion category C3 EN ISO 12944) however ZPRO has a much neater, shinier finish.
Economical too, ZPRO bridges the gap between standard glavanised steel and the considerably more expensive stainless steel material.

Installation
Installation
Fixing
On timber :
- CNA4.0 ring shank nails,
- CSA5.0 screws,
- Ø8 mm SSH screws,
- Bolts Ø8 mm.
On concrete :
- Chemical resin AT-HP
The distance between the plate and the concrete must be 50 mm maximum.
Installation
Upper part :
- Place the post in the postbase,
- Secure the post base to the post.
Lower part :
- Secure the post base to the post,
- Drill the support vertically, to the recommended diameter and depth,
- Position the post and finalize the fixing to the ground using adhesive,
- The column base can also be embedded in the concrete when the latter is poured.
