Steel Ladders & Ladder Beams

(Access & Structural Members)

Product Overview

SPAR is involved in the creation and production of steel scaffolding, ladders, and ladder beams that are the main factors for safe access and structural integrity in the assemblies of modular scaffolding. These parts are made from high-tensile steel tubes (EN 10219 S355) and are hot-dip galvanized to prolong the material's life, in line with Aramco GI 8.001 §5.6 (Access & Egress), SABIC §9.4, and BS EN 12811-1 standards.

ALTRAD SPAR’s ladder solutions ensure safe vertical and horizontal navigation of workers, and the ladder beams serve as long-span bridging elements for decking, cantilever, and suspended scaffolds.

Key Features & Advantages

Steel Access Ladders
