Sections of the panels are cut out where applicable to accommodate structural variations.
Cut-outs are included in square metre (m²) calculations.
Welding Specifications
A2B STANDARD WELDING SPECIFICATIONS:
Kick plate welded to transverse bars – The top half of each transverse bar is welded to the kick plate.
Kick plate welded to Bearer bars – Corners are welded on both sides and every Bearer bar is welded with an appropriate weld on one side.
Banding welded to Bearer bars – Corners are welded on both sides and every 4th Bearer bar is welded on one side with an appropriate weld. Every Bearer bar is tack welded on top.
Banding welded to transverse bars – The top of every transverse bar is welded to the flat bar, which forms the banding.
Please Note: We will gladly assist in adjusting our welding specifications to meet the clients needs, if requested, in the event that the specifications exceed our norm.
