[Sales and Leasing] Dramatically improves the workload during installation and removal due to simple design and lightweight construction! Also contributes to addressing the aging issues in scaffolding work!

Are you troubled by the aging workforce in scaffolding construction? The stair opening handrail frame used for fall prevention from stair openings. The "Aluminum Step Guard" stair opening handrail frame from Chuo Built Industry is a 6.2 kg handrail frame that is approximately 60% lighter than our conventional steel products.

[New Product Announcement] Stair Opening Handrail 'Aluminum Step Guard'

  • Product news

The conventional "step guard" was very heavy, causing significant burdens on-site. The new product, the aluminum step guard for stair openings, has switched the main material from steel to aluminum, achieving a weight reduction from 14.8 kg to 7.8 kg, approximately 47% lighter. This dramatically reduces the burden on the worksite and significantly improves work efficiency, contributing to shorter construction periods. Additionally, the arm can be opened and closed at a 90-degree angle, eliminating the previously existing triangular opening and greatly enhancing safety. More details are available in related products and catalogs. 【Features】 ■ Wedge-locked scaffolding (next-generation scaffolding) ■ Proven track record with major leasing companies ■ Hook locking mechanism improves efficiency in disassembly with one-sided operation ■ Prevents falls from stair openings ■ Certified compliant product by the Temporary Construction Industry Association
