Certified Fittings & Scaffold Accessories
Every reliable scaffolding structure relies on high-integrity connections. Malmo Steels manufactures a complete range of BS 1139 / EN 74 compliant drop-forged and pressed steel couplers designed to securely connect standard 48.3 mm tubes at any angle or fixed 90° orientation.
Alongside coupler fittings, Malmo supplies modular masonry frames including Italian frames and ladder frames with tubular cross braces, multi-board transoms, continuous rolled tie rods, and full mill-certified scaffold tubes in black self-finish and hot-dip galvanized executions.
Quality & Testing Assurance
- Drop Forged Durability — High-yield carbon steel forging prevents brittle failure under extreme torque and cyclical loads.
- EN 74 Slip Resistance — Couplers are rigorously batch tested to exceed European slip and distortion requirements.
- Corrosion Protection — Zinc electroplating (yellow or clear passivated) and hot-dip galvanizing available across all items.
- Precision Mill Tubes — EN 39 / BS 1139 scaffold tubes tested for tensile strength, elongation, and flattening resistance.
