The 40 x 40mm Square Pipe Infill Weld Stanchion (12.7mm) brings the geometric precision of a square post profile together with the permanence of a fully welded infill system. Pre-drilled to accept 12.7mm round infill tubing, this stanchion is the ideal choice for installers who want the architectural confidence of a square post with a fine, densely spaced infill that is locked permanently in place.
The visual contrast between the strong 40 x 40mm square post and the slender 12.7mm infill tubes is particularly striking — the bold post anchors the design while the delicate infill runs create a detailed, layered pattern that reads as carefully considered and professionally executed. This combination suits contemporary homes, commercial spaces, and architectural feature balustrades where design quality is a priority.
Welding is limited to securing the infill tubes within the pre-drilled post holes — the post bolts down to the ground via the included flange with no floor welding required. Each pack includes the base plate, cover plate, and saddle bracket. Infill tubing, top rail, fixing hardware, and end caps are all sold separately.

Which Grade Should I Choose?
Grade 304 is strong and reliable, suited to internal applications and external use in non-coastal, non-corrosive environments — ideal for inland areas such as Johannesburg, Pretoria, and most non-coastal suburbs.
Grade 316 (Marine Grade) offers superior corrosion resistance and is the essential choice for coastal properties, poolside installations, and any environment exposed to salt air, moisture, or chemicals. If you are in Cape Town, the Winelands, Durban, or any coastal area, Grade 316 is strongly recommended.
