Description
Our cable tray system is manufactured from galvanized steel sheet, designed for heavy-duty cable management in industrial environments. Available in ladder, trough, and solid-bottom configurations, each tray features precision-punched mounting holes, roll-formed edges for rigidity, and compatible fittings (elbows, tees, reducers). The hot-dip galvanized finish (70-100μm) ensures long-term corrosion protection in humid, chemical, and outdoor environments. All trays are load-tested per NEMA VE 1 standards.

Manufacturing Notes
Cable tray performance comes down to two things: the section stiffness that lets it span between supports, and the galvanizing that lets it last outdoors. Both are fixed at the sheet stage.
- Sheet thickness: 1.0mm to 2.0mm depending on span and load class. Thickness is chosen from the support spacing you specify, not from habit — a 1.0mm tray at 1.5m support centres will sag visibly under a loaded cable run.
- Roll-formed edges: The side rails are roll-formed rather than bent on a press brake, which gives a continuous stiffening return along the full length and keeps the profile consistent over a 3m run.
- Perforation and fittings: Mounting holes and rung slots are punched on a CNC turret so hole positions repeat along the tray, and matching elbows, tees and reducers are made from the same programme.
- Galvanizing: Pre-galvanized sheet for indoor runs, hot-dip galvanizing at 70–100μm for outdoor, humid or chemically exposed installations. Cut edges on pre-galvanized trays are cold-repaired with a zinc-rich compound.

Inspection & Quality Control
Trays are inspected per batch, and because trays are installed in runs, straightness and hole alignment matter as much as individual dimensions.
- Incoming material: Zinc coating weight verified on the incoming coil; sheet thickness checked with a micrometer.
- Dimensional and alignment: Length, width, height and hole pitch checked against the drawing on the first article. Hole alignment is checked by bolting three trays together end to end.
- Straightness: Each tray checked against a straight edge; a tray that will not sit flat over 3m is rejected before galvanizing, since distortion after hot-dip is far harder to correct.
- Load validation: Sample trays load-tested to the declared NEMA VE 1 class at the specified support spacing before the batch is released.
- Galvanizing: Coating thickness measured at several points with a magnetic gauge; adhesion checked and the surface inspected for bare patches or excess zinc build-up at the ends.

Frequently Asked Questions
Which support spacing should we specify?
Send us the cable load per metre and the span between supports and we will confirm the correct thickness and load class. As a rule, heavier loads or wider spacing push you up one thickness step rather than requiring a different profile.
Can you supply the fittings as well as the straight sections?
Yes. Elbows, tees, reducers, couplers and wall brackets are produced from the same punching programme so hole patterns match the straight lengths. Mixed loads ship together.
Pre-galvanized or hot-dip galvanized?
Pre-galvanized for indoor and covered plant rooms; hot-dip for outdoor, wash-down, coastal or chemical environments. Hot-dip gives 70–100μm and is the right choice where the tray will see moisture.
What is the MOQ?
50 pieces for a mid-size fabricated part. For a project with several profiles and fittings, the MOQ applies per profile rather than to the order as a whole.
