Welded Masonry Support
The welded system is ACS’s most widely specified masonry support, a continuous shelf angle with welded brackets suited to cavities of 50mm and above.

General Guidance
Fixed Back to Concrete & Cast-In Channel
Fixed Back to Concrete
Bolts directly to a concrete structure via expansion or chemical fixings. One of the most commonly specified configurations across residential, commercial and high-rise. Three-axis adjustment via Alpha II vertical adjustment, horizontal gap between angle lengths and stainless steel or thermal shims for cavity width.
Fixed Back to Cast-In Channel
Fixed back to ACS 31/21 AXIS cast-in channel via T-head bolts. The preferred configuration for continuous horizontal adjustment along the channel, with faster on-site installation and no on-site drilling into the structure.

Fixed Back to Structural Steel
Fixed Back to Steel UB
Bolts to universal beams via welded plates or tees using hex head setscrews. The standard configuration for steel frame construction. Where dissimilar metals are in contact, we recommend isolation gaskets between bracket and beam and top hat washers between fixing bolt and drilled hole – both available from ACS.
Fixed Back to RHS
Bolts to the face of rolled hollow sections via blind bolts. Particularly suited to steel frame structures where access behind the fixing face is restricted. Same shelf angle and bracket assembly as our other configurations, with fixing engineered for limited access fixings. Where dissimilar metals are in contact, we recommend isolation gaskets between bracket and RHS and top hat washers between fixing bolt and drilled hole – both available from ACS.
Alternative Configurations
Fixed Back to Concrete Top Cleats
Hex head sets screws bolt the bracket assembly back to cleats fixed to the top of concrete slabs via expansion bolts or chemical fixings. Specified where face drilling to the structure isn’t possible – including party wall locations.
Inverted Masonry Support
Same shelf angle and bracket assembly with the angle located above the fixing points. Specified where architectural detailing requires the masonry to be supported from above rather than below – typically at pier and window-reveal details. Integrated reveal support available as a single fabricated component.
Bespoke and Specialist Solutions
Projected Masonry Support
Bracket assembly that drops the shelf angle down to window head level, supporting the masonry directly over the opening and removing the need for a separate lintel. Particularly useful where spandrel panel heights are small and there isn’t room for a conventional lintel-and-support arrangement – projection length, bracket geometry and fixing arrangement engineered to your detail.
Masonry Support Specials
Designed and manufactured in-house by our Technical Engineering Team, bespoke systems engineered to solve the most unique and architecturally challenging details, where standard configurations won’t do.
More Than a Manufacturer. A Compliance Partner.
Every ACS customer benefits from ACS Assured – our framework built on three pillars: Compliance Through Expertise, Assurance Through Transparency, and Performance & Innovation. From Gateway 2 documentation to full product traceability and sustainable manufacturing credentials, it’s built into everything we supply.

Masonry Support Specials and Bespoke Design
When the standard range can’t accommodate the demands of a project due to high loadings, unusual geometry, cavity constraints or complex movement requirements, our in-house structural engineers design fully bespoke masonry support systems engineered for the specific detail. Share your drawings and loadings with our Technical Engineering Team and we’ll develop a solution to meet the demands of your detail.
Masonry Support CPD
ACS runs a RIBA-accredited CPD on masonry support systems covering when to specify bracket and angle vs continuous angle, fixing configurations across concrete, steel and cast-in channel substrates, cavity and movement detailing. Available online or in person. Book your place, or get in touch to arrange a session for your team.
Tested, Certified, Trusted
Our bracket and angle, and continuous angle masonry support systems are independently tested and certified to UKCA, CE and CE+UKNI marking, fabricated to BS EN 1090, and CCPI certified for clear, accurate product information.
