Building Steel

Building steel provides the essential structural reinforcement that modern construction demands. From residential foundations to large-scale commercial projects, steel reinforcement ensures concrete structures can withstand tension, compression, and the stresses of everyday use. Whether you're laying a simple garden slab or constructing load-bearing walls, the right steel components are fundamental to achieving a safe, durable, and code-compliant build.

Our Building Steel Range

McMahons stocks a comprehensive selection of steel reinforcement products to meet diverse construction requirements:

• Rebar (reinforcing bar) in various diameters for concrete reinforcement, offering excellent tensile strength for foundations, columns, and beams
• Steel mesh sheets and rolls for slab reinforcement, reducing cracking and distributing loads evenly across concrete surfaces
• Tie wire and bar chairs to secure reinforcement in position before pouring, ensuring correct cover depth for structural integrity
• Lintels and structural steel sections for supporting openings in masonry walls, available in standard and custom lengths

Steel reinforcement works hand-in-hand with proper drainage planning—explore our full Civil Drainage Systems range to ensure your groundworks are fully prepared.

Selecting the appropriate steel depends on your project's load requirements, concrete cover specifications, and environmental exposure. Consider bar diameter, spacing recommendations from your engineer, and whether galvanised or epoxy-coated options are needed for corrosive conditions.
