Types Of Steel Grating

Types Of Steel Grating

Types Of Steel Grating

1. Сварная стальная решетка

  • The most widely used type.

  • Bearing bars and cross bars are welded at intersections.

  • Strong, durable, and suitable for heavy load-bearing uses like platforms, walkways, and trench covers.

2. Press-Locked (or Pressure-Locked) Steel Grating

  • Bearing bars and cross bars are mechanically pressed and locked together without welding.

  • Provides a clean, uniform appearance.

  • Commonly used in architectural applications such as facades, fences, and decorative screens.

3. Swage-Locked Steel Grating

  • Cross bars are inserted and swaged into pre-punched bearing bars.

  • Offers tight tolerances and good strength.

  • Often used in high-precision or architectural projects.

4. Rivet-Bonded Steel Grating

  • Bearing bars and cross bars are joined by riveting.

  • Provides extra strength and durability.

  • Suitable for heavy-duty industrial environments and areas with dynamic loads.

5. Surface Types

  • Plain Surface Grating – smooth top, general use.

  • Serrated Surface Grating – notched top for slip resistance, ideal for wet or oily areas.

  • I-Bar Grating – lighter weight, designed for strength with reduced material usage.

Steel Grating Material

1. Carbon Steel

  • The most widely used material for steel grating.

  • Offers excellent strength and cost-effectiveness.

  • Often hot-dip galvanized or painted to improve corrosion resistance.

  • Suitable for industrial flooring, trench covers, walkways, and platforms.

2. Stainless Steel

  • Provides superior corrosion and rust resistance.

  • Ideal for harsh environments such as marine, food processing, chemical plants, and outdoor installations.

  • More expensive but offers long service life with minimal maintenance.

  • Available in grades such as 304 and 316 stainless steel.

3. Galvanized Steel

  • Carbon steel grating coated with a protective zinc layer by hot-dip galvanizing.

  • Strong, durable, and corrosion-resistant, suitable for outdoor or wet environments.

  • Commonly used in construction, drainage covers, and public infrastructure.

4. Aluminum (sometimes used as an alternative)

  • Lightweight, corrosion-resistant, and non-magnetic.

  • Easier to handle but less load-bearing than steel.

  • Used in architectural designs, marine environments, and lightweight platforms.
