Guard Frame: Component Specs, Materials & Applications

Component Specifications

Definition

A rigid structural assembly designed to enclose hazardous areas of industrial machinery, preventing operator contact with moving parts, hot surfaces, electrical components, or process materials. It serves as the primary mounting structure for safety panels, mesh, or transparent barriers while maintaining structural integrity under operational stresses.

Working Principle

Creates a physical barrier between operators and machine hazards using structural rigidity and proper mounting. The frame absorbs impact forces, supports protective materials, and integrates with machine controls through interlock systems that halt operation when access doors are opened.

Materials

Galvanized steel (S235JR/S355JR), powder-coated mild steel, aluminum alloy (6061-T6), or stainless steel (304/316) depending on environmental conditions. Minimum thickness: 2mm for steel, 3mm for aluminum.

Technical Parameters

Parameter	Typical range	Notes & selection driver
Access Doors	Hinged or sliding with safety interlocks
Mesh Opening	Maximum 12mm (ISO 13857)
Frame Profile	40x40mm or 50x50mm square tubing
Load Capacity	Minimum 500N static load
Mounting Type	Bolted or welded to machine base
Height Requirement	Minimum 1800mm for overhead protection
