IG WMS is a rigid masonry support system comprised of a stainless steel angle support shelf with fixed brackets. It is designed to accommodate loads up to 22 kN/m and bespoke fixing applications. The system is fabricated to engineers' specifications on a project specific basis. The system is suitable for cavity widths 50mm to 290mm.

IG's team of engineers offer a bespoke design service including onsite technical assistance.

The Welded Masonry Support system provides significant adjustability on two planes to ensure building tolerances can be accommodated and contact with structural reinforcing can be avoided. A toothed lock washer inserted into a serrated slot in the support bracket accommodates adjustability on the Y axis. Shims can be inserted between the support structure and the bracket giving adjustability along the Z axis. The 2 mm shims are provided as standard.

IG's range of masonry support products can be supplied with brackets to accommodate a range of applications.

Features and benefits:

  • Extra strength to support extreme loads exceeding 14 kN/m.
  • Can be supplied with brackets to accommodate a variety of configurations.
  • Onsite adjustability, significant adjustment on two axes.
  • Vertical adjustment of ±15 mm is achievable via the toothed lock washer. Fine adjustment is achieved by rotating the washer through 180°.
  • To accommodate a small increase in cavity width, up to three shims can be inserted between the support structure and the bracket (12 mm maximum).

Off plumb adjustment with patented wedged shim.

  • Ease of installation.
  • Suitable for cavity widths: 50–290 mm (Consult IG technical team for cavity widths exceeding 150 mm).
  • CE marked to BS EN 1090-1.
  • NSAI marked to IS EN 1090-1
