Overview
Engineered specifically for glass curtain wall support systems, our precision‑manufactured square steel tubes are fitted with integrally welded end plates at both ends. The distinctive “chocolate‑bar” surface texture—with clean, evenly spaced grooves—transforms a functional structural component into an elegant architectural feature, perfectly suited for landmark facades in the UAE and the wider Gulf region.
Material & Specifications
Steel Grade: Q355B high‑strength structural steel (compliant with GB/T 1591 and equivalent international standards).
Section: Square hollow section, available in custom sizes and wall thicknesses to match your design loads.
End Plates: Factory‑welded flat or slotted plates, precisely aligned for accurate bolting on site.
Surface Pattern: Precision‑machined chocolate‑style grooving that provides a refined decorative finish while preserving full load‑bearing capacity.
Corrosion Protection – Duplex Coating System
To withstand the extreme heat, intense UV radiation, and coastal salinity of the Middle East, every product is protected by a dual‑layer system:
Hot‑dip galvanising (minimum 85 µm) – provides robust cathodic protection against corrosion.
High‑build paint topcoat – applied over the galvanised surface (typically epoxy primer + polyurethane or fluorocarbon finish) for enhanced UV resistance, colour retention, and an extra barrier against moisture and abrasion.
This duplex combination ensures long‑term durability with minimal maintenance, meeting the most demanding façade specifications.
