Molded Reinforced Cable Tray

Molded Reinforced Cable Tray,also known as molded cable trunking,is a new generation energy-saving cable support system manufactured through one-time high-pressure stamping and molding technology.Different from conventional flat steel cable trays with simple bending structure,this product adopts integrated corrugated reinforcing rib molding on the base and side panels,forming a three-dimensional load-bearing structure that greatly upgrades mechanical performance while cutting raw material consumption.It can be produced with cold rolled steel,galvanized steel,stainless steel and SMC fiberglass composite materials,widely applied for routing,supporting and protecting power cables,communication wires and control cables in all kinds of industrial and construction projects.

The core molding process determines its outstanding structural advantages.The whole tray body is stamped into continuous transverse reinforcing ribs by large-tonnage hydraulic presses,which raises the axial moment of inertia and lateral rigidity significantly.Test data proves that its bending and torsion resistance is improved by over 30%compared with ordinary cable trays of equal thickness;even thinner sheet can achieve higher load capacity,saving 30%–40%steel materials and reducing overall weight effectively.Unique R-groove design on side flanges prevents lateral instability under heavy cable loads,avoiding deformation or collapse during long-term service.All sections are integrally molded without secondary welding,eliminating welding cracks,rust-prone weld seams and uneven flatness problems of traditional welded trays.

Diversified material and surface treatment options satisfy diverse working environments.Metal molded trays support hot-dip galvanizing,electro-galvanizing,powder coating,fluorocarbon spraying and VCI anti-corrosion coating,delivering superior anti-rust and salt-spray resistance for coastal,humid and chemical plant sites.SMC fiberglass molded cable trays are made of sheet molding compound via high-temperature compression molding,featuring full insulation,acid&alkali corrosion resistance,flame retardancy and low thermal conductivity,ideal for petrochemical,power plant and new energy charging stations where electrical isolation is required.Every finished product has smooth surface without burrs or sharp edges to prevent cable insulation scratch.

This series covers complete standardized accessories to form a full wiring system,including straight sections,horizontal elbows,tees,crosses,vertical risers,separating baffles and matching cover plates.Modular design allows fast on-site assembly with simple connecting bolts,cutting construction period and labor cost.The hollow corrugated bottom creates natural air convection channels between cables and tray base,boosting heat dissipation efficiency,lowering cable operating temperature and reducing power loss,which perfectly fits green building and energy-saving engineering standards.Additional anti-slip texture on molded surfaces improves safety for overhead installation and maintenance work.

Molded reinforced cable trays are widely adopted in data centers,subway tunnels,municipal pipe galleries,photovoltaic power stations,chemical factories,power substations,commercial complexes,hospitals and new energy vehicle projects.They meet strict industrial standards for load capacity,fire resistance and anti-corrosion.Our factory provides customized sizes from 50mm to 900mm in width,lengths ranging 2–12 meters,and accepts OEM non-standard specifications according to construction drawings.All raw materials and finished goods go through strict inspection including load deflection test,salt spray test and flatness detection to guarantee long service life and stable operation of cable transmission systems.
