Top 10 Cable Tray Roll Forming Equipment Manufacturers in China (In No Particular Order)

Cable tray systems are used to support, route, separate, and protect electrical cables in industrial facilities, photovoltaic plants, commercial buildings, subway systems, data centers, and petrochemical installations. These systems normally consist of continuous steel channels with perforated bases, folded sidewalls, connection slots, and reinforcement ribs. The geometry of the tray determines cable load distribution, heat dissipation performance, and structural rigidity during long-span installation.

The manufacturing process for cable trays has gradually shifted from segmented press brake fabrication toward continuous roll forming. In roll forming production, steel coil passes through sequential roller stations that progressively bend the strip into a finished tray profile while maintaining dimensional continuity. This process reduces sidewall deviation, improves hole positioning consistency, and minimizes edge distortion around punched sections.

China has become one of the largest manufacturing centers for cable tray roll forming equipment due to its steel processing supply chain, bearing manufacturing capacity, servo control integration, and industrial automation infrastructure.

Among Chinese manufacturers, IUWON Roll Forming Machinery has developed a specialized product category focused on cable tray production systems rather than generic roofing machinery. Its equipment portfolio includes perforated cable tray lines, ladder tray production systems, trunking roll forming machines, and heavy-gauge industrial tray lines designed for electrical infrastructure manufacturing.

This article reviews ten Chinese cable tray roll forming machine manufacturers, with detailed engineering analysis focused on IUWON's machine structures, production logic, forming systems, and industrial applications.

IUWON manufactures coil-fed cold roll forming systems designed for structural steel profile production. In the cable tray sector, the company focuses on continuous forming equipment capable of integrating punching, embossing, sidewall bending, inline cutting, and automatic stacking into one production workflow.

The machines are designed to process galvanized steel, hot-dip galvanized steel, stainless steel, aluminum strip, and zinc-aluminum-magnesium coated steel. Typical material thickness ranges between 0.8 mm and 3.0 mm depending on tray load requirements and installation environment.

Unlike manual fabrication methods where operators separately punch, shear, and bend tray sections, IUWON's production lines maintain continuous material flow from coil feeding to finished tray discharge.

This production architecture reduces alignment error between perforation patterns and sidewall geometry.

Perforated cable trays contain repeated slot patterns across the tray bottom and sidewalls. These openings reduce cable heat accumulation and allow installers to fasten cable ties or clamps through the tray structure.

IUWON's perforated cable tray lines generally include:

Hydraulic decoiler

Coil leveling section

Servo feeding system

Hydraulic punching station

Main roll forming section

Hydraulic cutting unit

Discharge table

The punching station creates elongated ventilation slots and connector holes before the material enters the roller section.

Punching before forming reduces distortion around slot edges because the strip remains flat during hole formation.

The forming section gradually bends the strip into U-shaped or reinforced tray geometry through sequential roller stations.

Common tray dimensions include:

Width: 100–800 mm

Sidewall height: 50–150 mm

Material thickness: 1.0–2.5 mm

The rollers are typically manufactured from Cr12Mov steel with heat treatment to reduce wear caused by continuous galvanized steel contact.

These machines are commonly installed in electrical infrastructure factories supplying:

Commercial building cable systems

Industrial motor control centers

Photovoltaic inverter routing systems

Data center cable distribution networks

Ladder cable trays use two longitudinal side rails connected by repeated transverse rungs. This structure increases ventilation around high-current power cables and reduces cable heat retention during continuous electrical loading.

IUWON's ladder tray systems normally manufacture:

Side rails

Reinforcement flanges

Cross-rung structures

The production process usually separates side rail forming and rung insertion into different stages.

The side rails are produced through roll forming while transverse rungs are welded or mechanically fixed afterward.

Typical side rail thickness ranges from 1.5 mm to 3.0 mm depending on span length and cable weight.

The formed side rails often include:

Return lips

Stiffening ribs

Connector slots

Suspension holes

The ribs increase section modulus and reduce sidewall deflection during suspended installation.

These systems are commonly used in:

Petrochemical plants

Transformer stations

Underground subway systems

Thermal power plants

In these environments, the tray structure must support heavy copper cable bundles over long suspended distances.

Cable trunking systems enclose electrical wiring inside fully or partially covered steel channels. Compared with open tray systems, trunking structures reduce dust accumulation and provide limited physical shielding against mechanical impact.

IUWON's cable trunking production lines form:

Base channels

Snap-fit covers

Reinforced edges

Connector joints

The machines usually process thinner galvanized strip between 0.6 mm and 1.5 mm thickness.

The forming rollers create locking edge geometry that allows the cover section to mechanically engage with the base channel.

This configuration reduces the need for external fasteners during installation.

In commercial buildings, trunking systems route low-voltage wiring above suspended ceilings or below raised flooring systems.

Heavy-duty cable tray systems are used in industrial environments where tray spans exceed 3 meters or cable bundles contain high-current conductors.

IUWON's heavy-duty tray machines process steel thicknesses up to 3.0 mm depending on profile geometry.

The production lines normally include reinforced gearbox transmission systems because thicker steel generates higher forming resistance across roller stations.

The tray sections generally contain:

Bottom reinforcement embossments

Multi-step sidewall geometry

Return edge structures

Load-bearing flanges

Embossments increase tray rigidity by distributing bending stress across the base surface.

These trays are frequently installed in:

Offshore platforms

Cement plants

Mining facilities

Steel mills

In these environments, cable trays are exposed to vibration, suspended dust, humidity, and elevated ambient temperatures.

Photovoltaic power plants contain long cable routing paths between combiner boxes, inverters, transformers, and battery storage systems.

IUWON manufactures cable tray systems specifically configured for solar infrastructure applications.

These trays commonly use:

Zinc-aluminum-magnesium coated steel

Hot-dip galvanized steel

Perforated ventilation structures

The coating resists corrosion in outdoor environments exposed to rainwater, fertilizer residue, coastal salt spray, or desert humidity cycling.

The tray structures usually integrate slotted mounting holes compatible with photovoltaic support channels.

This reduces secondary drilling during installation.

IUWON cable tray production systems generally use continuous coil-fed processing rather than segmented sheet feeding.

The workflow normally follows:

Coil loading

Hydraulic unwinding

Strip leveling

Servo feeding

Punching

Roll forming

Hydraulic cutting

Finished tray discharge

Each roller station applies incremental deformation to the strip profile.

This forming sequence reduces localized stress concentration near folded corners.

The roller spacing, sidewall angle progression, and flange transition geometry directly affect tray straightness after cutting.

If deformation between adjacent stations becomes excessive, edge waviness or sidewall twisting may occur.

Cable tray production requires repeated hole patterns for ventilation, cable fastening, and suspension assembly.

IUWON typically integrates hydraulic or servo punching systems before the roll forming section.

The punching dies produce:

Round holes

Elongated slots

Mounting openings

Connector holes

Servo feeding systems synchronize strip movement with punching cycles to maintain hole pitch consistency.

In long cable tray assemblies, inconsistent hole spacing can prevent connector alignment during field installation.

The machines are generally configured for:

GI steel

HDG steel

Stainless steel 304

Stainless steel 316

Aluminum strip

ZAM-coated steel

Stainless steel trays are commonly used in:

Food processing plants

Pharmaceutical factories

Coastal desalination facilities

These environments expose tray surfaces to washdown chemicals, chloride vapor, or condensation.

Aluminum trays reduce structural dead weight in suspended installations inside commercial buildings.

Cable trays are typically installed through:

Ceiling suspension rods

Wall-mounted brackets

Raised floor support systems

Outdoor steel support structures

The tray sidewalls transfer cable weight into support brackets.

Long-span tray systems may require reinforced ribs to reduce center deflection.

In thermal power plants, tray systems route cables near steam piping where ambient temperatures can exceed 50°C.

In petrochemical environments, galvanized coatings may gradually deteriorate due to sulfur-containing airborne compounds.

Cable tray systems primarily experience failure through:

Coating corrosion

Sidewall buckling

Connector loosening

Edge cracking

Tray sagging

Corrosion generally begins around punched edges where protective coating thickness becomes discontinuous.

For roll forming equipment, maintenance operations usually include:

Roller lubrication

Bearing replacement

Punching die sharpening

Hydraulic seal inspection

Chain tension adjustment

Punching dies experience concentrated wear because repeated slot production creates localized compressive stress.
