Sigma RTM protective handrails made of 33.7×2.25 mm pipes are a key safety and health and safety component for safety on scaffolding. To the pipes are welded o-heads equipped with wedges, which allow easy and quick installation of the handrails. These handrails serve as longitudinal and transverse side protection, protecting users from accidental fall from the scaffolding structure.

Corrosion protection of the bracing was done by hot-dip galvanizing, which significantly extends their durability and resistance to weathering.
