Introducción

Dense welded steel grating is a high-strength, durable grating option designed with closely spaced bearing bars. This type of grating is particularly suitable for applications requiring small openings, enhanced load capacity, and improved safety. Due to its structural integrity, dense welded steel grating is widely used in industrial plants, walkways, stair treads, and other facilities where strength and security are paramount.

This document provides a comprehensive overview of dense welded steel grating, including detailed specifications, available models, dimensional information, and other essential factors.

1. Specifications of Dense Welded Steel Grating

1.1. Material Composition

• Acero carbono: Provides excellent strength and durability, ideal for heavy-duty industrial applications.

• Acero inoxidable: Offers superior corrosion resistance, suitable for environments exposed to chemicals or moisture.

• Acero galvanizado: Coated with a zinc layer for enhanced corrosion protection in outdoor and industrial applications.

1.2. Surface Finish

• Galvanizado por inmersión en caliente: The most common finish for corrosion protection.

• Recubrimiento en polvo:Ofrece protección adicional y personalización estética.

• Acabado de molino: Provides a clean steel appearance, primarily for indoor use.

1.3. Welded Construction

• Dense welded steel grating is produced by welding the bearing bars and cross bars together under pressure.

• This welding process results in a strong and rigid panel that can withstand heavy loads and impacts.

2. Modelos y tipos

2.1. Based on Bearing Bar Profile

• Flat Bar Grating: Provides a standard load-bearing capacity and uniform appearance.

• Serrated Bar Grating: Features a serrated surface for enhanced slip resistance.

• I-Bar Grating: Reduces weight without compromising strength.

2.2. Based on Bar Spacing

• 19-W-4 Grating: Standard bar spacing with wider openings.

• Dense Spacing Grating (11-W-4 or 7-W-4): Closely spaced bearing bars, commonly used for ADA compliance and increased safety.

2.3. Specialty Types

• Heavy Duty Dense Grating: Designed for applications requiring extreme load-bearing capacities.

• Custom Fabricated Grating: Manufactured according to specific design and project requirements.
