Horizontal Rail for Safety Barriers

Product Specifications

Technical details and manufacturing context for Horizontal Rail

Definition

The horizontal rail is a critical load-bearing component within a safety barrier frame system, designed to absorb and distribute impact forces while preventing personnel or objects from passing through designated boundaries. It typically runs parallel to the ground and connects to vertical posts to form a rigid protective structure. This directory entry covers horizontal rails used in fabricated metal product manufacturing, specifically as part of safety barriers. The rail's primary function is to transfer applied loads, such as impacts or pressure, along its length to the connected vertical posts and ultimately to the foundation. Its structural integrity and material strength determine the barrier's ability to withstand forces without permanent deformation or failure. Available materials include galvanized steel, stainless steel, and aluminum alloy. Key parameters include length (2000–6000 mm), height (100–200 mm), wall thickness (2.0–4.0 mm, per GB/T 6728), material grade (Q235B–Q355B, per GB/T 700), surface treatment (HDG 70–85 μm, per ISO 1461), impact resistance (≥50 kJ/m², per ISO 179), yield strength (235–355 MPa, per GB/T 1591), tensile strength (370–630 MPa, per GB/T 1591), straightness tolerance (≤0.1% per meter, per ISO 2768-1), cutting tolerance (±1.0 mm, per ISO 9013), weight (5–15 kg/m), operating temperature (-40–80 °C), and corrosion resistance (≥1000 h salt spray, per ISO 9227). These values are reference ranges and must be confirmed for the specific model and application. Always verify with the legal manufacturer or supplier.

Working Principle

The horizontal rail functions by transferring applied loads along its length to the connected vertical posts and ultimately to the foundation. When an impact or pressure is applied, the rail bends and distributes the force across multiple support points, reducing stress concentration. The material's yield strength and wall thickness determine the maximum load before permanent deformation. The rail's cross-section and connection method influence its stiffness and load-bearing capacity. Proper installation and alignment are critical to ensure effective load transfer and prevent failure.

Frequently Asked Questions

What materials are available for horizontal rails?

According to the directory, horizontal rails can be made from galvanized steel, stainless steel, or aluminum alloy. The choice depends on the required strength, corrosion resistance, and environmental conditions.

What are the typical length and height ranges?

The directory lists a length range of 2000–6000 mm and a height range of 100–200 mm. Custom lengths may be available, but these values should be confirmed with the supplier.

Which standards are referenced for material and testing?

Standards include GB/T 6728 for wall thickness, GB/T 700 for material grade, ISO 1461 for surface treatment, ISO 179 for impact resistance, GB/T 1591 for yield and tensile strength, ISO 2768-1 for straightness tolerance, ISO 9013 for cutting tolerance, and ISO 9227 for corrosion resistance. These are reference standards for verification.

How should I verify the rail's suitability for my application?

You must check the specific model's parameters, such as wall thickness, material grade, and impact resistance, against your load requirements. Always consult the legal manufacturer or supplier to confirm that the product meets your needs and complies with applicable standards.
