With the mass production of linear strip lights in offices, shadowless strip lights in shopping malls, and eye protection panel strip lights in classrooms, the hanging wire for lighting fixtures is no longer a simple auxiliary material, but a core accessory that determines project safety, service life, and appearance quality. Many lighting manufacturers and engineering purchasers often confuse load-bearing steel wire rope suspension wires with power supply wire suspension wires, and the material standards for the two types of suspension wires are completely different. This article subdivides the materials, applicable scenarios, and advantages and disadvantages of the entire category of long strip lamp suspension wires, providing selection references for lighting accessory manufacturers, engineering procurement, and lighting assembly plants.
1、 Load bearing main suspension wire (core load-bearing component of long strip lamp, with four mainstream substrates on the market)
The weight of the strip lamp is concentrated, and all tension is borne by the load-bearing suspension wire. The industry and commercial engineering are uniformly based on steel wire rope, divided into four material grades:
1. 304 stainless steel wire rope (preferred for engineering standard)
Core substrate: National standard 304 stainless steel multi strand twisting, wire strand structure 7 × 7, 1 × 19, conventional diameter 0.8mm -3.0mm, suitable for various long linear lights
Advantages: Contains chromium nickel alloy, self repairing passivation film, moisture-proof and rust proof; Indoor offices, damp shops, kitchens and bathrooms, and coastal projects can all be used; Tensile strength 1500-2000MPa, single piece can carry 10-80kg, long-term suspension does not sag, and is not easy to fatigue fracture; Non magnetic, does not interfere with LED driver circuits.
Process subdivision: Bare stainless steel rope, PVC/TPU environmentally friendly wrapped stainless steel rope. The outer layer of the plastic coating is available in black, white, transparent, and multiple colors. The scratch resistant lamp body and friction silent design make it a popular material for long strip lights in office buildings. The minimalist workwear provides a cleaner visual experience.
Applicable: Office strip lights, supermarket linear lights, exhibition halls without main lights, indoor fixtures for all scenarios.
