Product Overview

IG’s Welded Masonry Support (WMS) is a rigid masonry support system comprising fixed brackets welded to a stainless steel angle support shelf.

There are several variations of the standard IG WMS system which are designed and manufactured to engineers’ specifications on a project basis. These variations include:

WMS Standard – suitable for applications where the support level aligns with the base of the structural frame.
WMS Dropper – suitable for applications where the support level is below the line of the base of the structural frame.
WMS Cavity Closer – suitable for applications where the support level is in line with the base of the structural frame, and when a cover is required to the underside of the
angle support shelf to conceal the cavity in the building.
WMS Inverted – suitable for applications where the support level is in line with the top of the structural frame.
WMS Plaster Key – suitable for applications where the support level is in line with the base of the structural frame, and when a render finish is required to the underside of the angle support shelf.
WMS Notched – suitable for applications where the support level is below the line of the base of the structural frame and when the brackets need notched to avoid a clash
with another element within the building.

Each variation is designed to support brickwork and blockwork in a building façade and fix back to the structural frame of that building. Each system is supplied with lock washers, shims and fixings to aid installation.

WMS is designed and manufactured to engineers’ specifications on a project basis and offers three planes of adjustability onsite.

Certification and Accreditations

IG’s Welded Masonry Support systems are certified with the Code for Construction Product Information (CCPI) mark, thereby guaranteeing information clarity, accuracy, and regulatory compliance.

Adjustability

IG’s Welded Masonry Support provides adjustability on three planes to ensure that building tolerances can be accommodated and contact with structural reinforcing bar can be avoided.

Vertical adjustment
Vertical adjustment is offered by means of a toothed Lock Washer which is inserted into the serrated slot in the support bracket. The lock washer can be adjusted vertically to move the bracket higher or lower. The serrated area at the back of the bracket allows up to 15mm of adjustment in either direction on the vertical plane.

Lateral Adjustment
The Lock Washer also providers lateral adjustment via the oval-shaped hole in the washer. The fixing can be moved +/- 2mm laterally to allow for fine adjustment.

Shimming
To accommodate a small increase in cavity width, shims can be inserted between the support structure and the brackets. Thermal shims are provided as standard to reduce thermal bridging in a thickness of 2mm and stainless steel shims are available to order in a range of thicknesses (3, 4, 5 and 6mm).

Product Design and Testing

Masonry support falls within the scope of harmonised European Standard BS EN 1090-1:2009 +A1:2011 Execution of steel structures and aluminium structures: requirements for conformity assessment of structural components. IG Masonry Support comply with all Construction Product Regulations (CPR), UKCA and CE marking requirements of this Standard, including designs to EN 1993 (Eurocode 3) and external certification of factory production controls by an approved body.

IG Masonry Support is certified by the British Board of Agrément and Eurofins to undertake welded fabrication work to Execution Class 2 according to BS EN 1090-2:2018.

IG’s products are designed to guarantee and maintain structural integrity and durability throughout their service life.

A1 Non-combustible Materials

All IG Masonry Support’s masonry support systems are manufactured from 304/304L Austenitic Stainless Steel (1.4301/1.4307) or 316/316L (1.4401/1.4404) on request. Stainless steel is considered A1 fire-rated without the need for testing in accordance with the guidance of the European Commission Paper 96/603/EC as referenced in BS EN 13501-1:2018.

IG Masonry Support’s Thermal Shims are supplied as standard with every masonry support system and are A1 fire-rated having been tested and classified in reaction to fire in accordance with BS EN 13501-1:2018.

Thermal Conductivity

Approved Document L Volume 2 places specific emphasis on the performance of building details and the additional heat losses through linear thermal bridging. To support this requirement, all IG Masonry Support’s masonry support systems are manufactured from 304/304L Austenitic Stainless Steel (1.4301/1.4307) or 316/316L (1.4401/1.4404) on request. Stainless steel has among the lowest thermal conductivity of any metal at approximately 15 watts per kelvin per metre.

IG also supply a Thermal Shim as standard with every masonry support system, which must be located between the back of the bracket and the support structure.
