Metal cable trays (with covers & fittings)

Engineered for efficient cable management in any type of project: industrial halls, logistics centres, office buildings, data centres, retail, PV/EV infrastructure, and more.

Standard specifications

• Material thicknesses: up to 2.0 mm
• Standard length: 3 m (other lengths on request)
• Usable widths: 50 – 600 mm (intermediate/custom widths on request)
• Side heights: minimum 40 mm (other heights available based on load)

Materials & protection

• Pre‑galvanised steel / pickled steel
• Hot‑dip galvanised steel — for outdoor use/high corrosion class
• Electrostatic powder coating (RAL of your choice)
• Stainless steel AISI 304/316 — for high‑humidity/aggressive environments

Build variants

• Solid or perforated trays (perforations for ventilation and heat dissipation)
• Covers clip‑on/screwed
• Fittings and accessories: T, L (90° bend), X, reducers, couplers, end caps, fixing clamps, brackets, expansion pieces
• Deburred edges, optimised corner radii to protect cable sheaths

Performance & design

• Stiffening ribs/folds to increase admissible span load
• Compatible with wall, ceiling, threaded‑rod and C‑profile bracket fixings
• Batch/material traceability on request

Tray width (mm)	Side height (mm)	Sheet thickness (mm)	Length (mm)	Variant	Notes
50–200	40–60	0.8–1.2	3000	solid/perforated	optional covers
250–400	50–80	1.0–1.5	3000	solid/perforated	stiffening ribs
450–600	60–100	1.2–2.0	3000	solid/perforated	reinforced fixing / brackets recommended

Note: values are indicative. Dimensions, perforations, weights and admissible loads are validated per project (span, mounting method, cable load).

MAR-INA advantages

• Fast execution on modern machinery (cutting, bending, perforating)
• Short runs or volume production
• Full customisation (dimensions, perforations, coatings, installation kits)
• Custom embossing / batch marking

Ventilation channels & metal grilles

Metal grilles for ventilation ducts, technical floors, utility rooms or ventilation areas in industrial halls and buildings. Made from galvanised sheet with continuous slots for optimal airflow and good mechanical strength.

Standard models

Code	Dimensions (L × W × H) mm	Material	Vent slots	Thickness	Application
GCA-495	495 × 78.5 × 52	Galvanised steel	43 × 9 mm, along full length	2.0 mm	ventilation channel/technical floor
GCA-1100	1100 × 78.5 × 52	Galvanised steel	43 × 9 mm, along full length	2.0 mm	ventilation channel/technical floor

Manufacturing details & options

• Built from 2 mm galvanised sheet (options: HDG, RAL powder coat, stainless 304/316)
• Deburred edges, strength via folds; dimensional tolerances per approved drawing
• Standard slot geometry 43 × 9 mm (pitch and layout customisable on request)
• Fixing/joining holes at ends — per project
• Design and production for non‑standard lengths/widths/heights

Installation & operation guidelines

• Mount on an existing channel or on metal frames/decking
• Verify permissible load if the grille is in pedestrian/traffic areas
• Additional anti‑corrosion protection for outdoor/wet environments

Ordering & coding

For standard products use codes GCA-495 and GCA-1100. For special builds, send your drawing or dimensions (L × W × H, thickness, material, slot type, fixings).

Frequently asked questions

Can I order non‑standard widths/heights for cable trays?

Yes. We manufacture to special dimensions, including custom perforations and covers, based on the required load and mounting method.

Do you offer electrostatic powder coating?

Yes, we can supply RAL‑coloured parts coated after galvanising or directly on pickled steel, depending on environment and aesthetic requirements.

Do standard grilles support pedestrian traffic?

For typical ventilation uses — yes. For heavy/vehicular traffic, thickness, material and supports are validated in the project.

Do you supply fixing accessories?

Yes. Brackets, couplers, clamps, fasteners — as a bill of materials or preconfigured sets.
