XQJ is the standard series designation for cable trays in China, manufactured in accordance with JB/T 10216-2000 (Cable Tray Technical Standard). The XQJ-DJ Large Span series is specifically engineered for installations where support spacing reaches 6 meters (or longer) without intermediate supports, far beyond the 2-meter typical span of standard trays.

Key features:

• Heavy-duty construction with reinforced side rails (2.0–2.5 mm) and longitudinal stiffeners — high load capacity (100–250 kg/m working load) and strong anti-deflection performance, no sagging over long spans

• Fewer supports required — cuts material and labor costs, faster installation

• Available in hot-dip galvanized steel, stainless steel, aluminum alloy, or pultruded FRP (fiberglass, single-section length up to 8 m)

• Full accessory range: covers, elbows, tees, crosses, reducers, connectors and clamps

Typical applications: power plants, petrochemical plants, textile & machinery factories, metallurgy, public utilities, large-span plant roofs, exhibition halls, gymnasiums, subway tunnels and cable trenches.郑州现代桥架有限公司郑州现代电缆桥架厂Made-in-China.comAlibaba.com
