Construction Metal Forming

What Construction Metal Forming does

Construction Metal Forming (CMF) is a UK-based specialist manufacturer of cold-formed steel construction products, headquartered in Mamhilad, Monmouthshire, South Wales, and founded in 2005 originally as Composite Metal Flooring. The company operates a 30,000 sq.ft purpose-built manufacturing facility housing three dedicated roll forming production lines with a 2,000-tonne coil stocking bay and four 10-tonne overhead cranes, capable of up to 12,000 square metres of output per day on a two-shift basis. CMF's core offering is the MetFloor composite metal decking system in three successive generations — MetFloor 55, 60 and 80 — representing increasing unpropped spanning capability from 3.5m to over 5.0m, complemented by MetPurl purlin and side-rail systems, MetForm light gauge steel framing, MetMezz industrial mezzanines, CSC cold-headed composite shear studs, and FibreDeck fibre-reinforced composite slabs.

The product line rests on cold-formed steel roll forming technology validated through structural testing at Imperial College London and fire testing at Pavus under Steel Construction Institute (SCI) management. CMF is the only UK decking manufacturer whose entire MetFloor profile range holds SCI Assessed certification, and the company distributes free SCI-ratified design software and full technical literature to specifiers, with MetPurl macros integrated into Tekla Structures BIM software. FibreDeck was co-developed with Sika, combining Fibermesh microsynthetic and Novocon steel fibre reinforcement as an alternative to traditional mesh in MetFloor slabs.

Revenue is generated through direct sales from the South Wales facility and a multi-partner UK distribution and installation network including Studwelders Composite Floor Decks, Northern Steel Decking (Sheffield headquarters with Scotland regional office in Johnstone), Construction Metal Sales (CMS) for purlins and cold-rolled portal frames, and family-company MetStructures for offsite residential, hotel, care and student accommodation framing. End customers span commercial developers, main contractors, steelwork contractors, industrial and logistics developers (notably distribution centres), and modular construction clients. Pricing is not publicly disclosed and is project-based. CMF holds CE marking to Execution Class 3 under BS EN 1090, ISO 9001/14001/45001 certifications, and memberships in BCSA, SCI and the UK Metal Decking Association, and has installed more than 5 million square metres of MetFloor across over 2,000 projects in roughly the last decade.

Direct peers

• Tata Steel (ComFlor): UK-headquartered integrated steel producer and the largest direct competitor to CMF's MetFloor range via its ComFlor composite decking profiles, also offering purlins and structural decking with similar SCI-assessed certifications.
• Voestalpine Metsec: UK-based cold-formed steel manufacturer producing metal decking, purlins, and structural sections, competing head-to-head with CMF's MetFloor and MetPurl product lines in commercial and industrial construction.
• Hadley Group: UK cold-formed steel specialist manufacturing steel framing, profiled decking, and purlins for construction, overlapping directly with CMF's MetFloor, MetForm, and MetPurl offerings.

Broad incumbents

• Kingspan Group: Global building envelope and structural products giant offering insulated panels, steel decking, and engineered building systems; competes with CMF on large commercial and industrial projects where bundled solutions are procured.
• ArcelorMittal Construction: European steel and construction products division of ArcelorMittal producing roofing, cladding, decking, and purlins, providing cross-border competition to CMF on UK projects, particularly in logistics and commercial buildings.

Regional players

• SAB Profiel: Netherlands-based cold-formed steel roll-former producing purlins, cassette profiles, and structural sections; competes with CMF on UK industrial and logistics projects sourced from European suppliers.
• Joris Ide: Belgian-European steel building products manufacturer offering roof and wall cladding, decking profiles, and purlins, competing with CMF on UK projects sourced through European supply chains.
• Canam Steel: North American structural steel and steel joist manufacturer with comparable composite decking and cold-formed products; useful international comparable for product scope though not actively serving the UK market.

Others

• Studwelders Composite Floor Decks: CMF's authorised UK installation and distribution partner for MetFloor decking and CSC shear stud welding; not a competitor but a channel peer whose economics directly determine CMF's effective go-to-market reach in UK composite floor construction.
• MetStructures: CMF family-of-companies subsidiary formed in 2017 for offsite light gauge steel framing in residential, hotel, care, and student accommodation; an ecosystem participant that both consumes CMF framing and competes with independent modular framing suppliers.
