Steel din rail 35mm width

35mm steel DIN rail designed for reliable mounting of electrical and industrial components. Made from high-strength steel with excellent load capacity and corrosion resistance, it is ideal for control panels, switchgear, automation systems, circuit breakers, terminal blocks, relays, and power supplies. Standard 35mm width ensures universal compatibility with DIN-rail-mounted devices, making installation fast, secure, and efficient in industrial, commercial, and residential applications.

A 35mm steel DIN rail is mainly used as a standard mounting system in electrical and industrial installations. Its applications include:

Main Applications

  1. Electrical Control Panels

    • Mounting circuit breakers (MCB, RCCB)

    • Terminal blocks

    • Relays and contactors

    • Power supplies and transformers

  2. Industrial Automation

    • PLCs (Programmable Logic Controllers)

    • I/O modules

    • Industrial communication devices

    • Motor controllers

  3. Switchgear & Distribution Boards

    • Organizing and securing electrical components

    • Ensuring neat wiring and easy maintenance

  4. Building & Infrastructure Systems

    • HVAC control systems

    • Lighting control panels

    • Fire alarm and security systems

  5. Telecom & Data Cabinets

workshop-of-din-rail

The manufacturing equipment for a 35 mm steel DIN rail is mainly focused on metal forming, punching, and surface treatment. Below is a clear, industry-standard breakdown from raw material to finished product:

1. Raw Material Preparation

Equipment:

  • Steel decoiler / uncoiler

    • Holds and feeds steel strip (usually cold-rolled steel or galvanized steel)

  • Straightening machine

    • Removes coil stress and ensures flatness

2. Roll Forming (Key Process)

Equipment:

  • DIN rail roll forming machine

    • Gradually forms the 35 mm “top-hat” DIN rail profile

    • Includes multiple forming stations

    • High precision to meet EN 60715 standard

Why it’s important:

  • Ensures consistent width (35 mm)

  • Maintains strength and dimensional accuracy

3. Hole Punching / Slotting

Equipment options:

  • Inline punching press (hydraulic or mechanical)

    • Punches mounting holes or slots during roll forming

  • CNC punching machine (for flexible patterns)

Hole types:

  • Round holes

  • Slotted holes

  • Custom hole spacing (per customer request)

4. Cutting to Length

Equipment:

  • Flying shear / servo cut-off system

    • Cuts DIN rail to standard or custom lengths (e.g. 1 m, 2 m)

    • Allows continuous production without stopping the line

5. Surface Treatment

Common options & equipment:

A. Zinc Plating (Most Common)

  • Electroplating line

    • Corrosion resistance

    • Silver or yellow zinc finish

B. Hot-Dip Galvanizing

  • Galvanizing bath system

    • For outdoor or harsh environments

C. Pre-Galvanized Steel

  • No extra coating equipment needed

  • Uses galvanized coil directly

D. Powder Coating (Optional)

  • Powder coating line + curing oven

    • Used for special color or added protection

6. Quality Inspection

Equipment:

  • Profile gauges / calipers

  • Load-bearing test fixtures

  • Salt spray testing chamber (for corrosion resistance)

  • Visual inspection stations

7. Packaging

Equipment:

  • Automatic stacking machine

  • Shrink wrapping machine

  • Carton or pallet packing line

Typical Full Production Line Setup

  1. Decoiler

  2. Straightener

  3. Roll forming machine

  4. Punching system

  5. Flying shear

  6. Surface treatment line

  7. Inspection & packaging

Standards Followed

  • EN 60715 (DIN rail standard)

  • IEC / RoHS (material & compliance)
