Machine guarding panels

Guarding Panels for Machine Safety: Mesh, Polycarbonate and Solid Steel

What are modular guarding panels for industrial machine safety?

Guarding panels form the structural basis of machine guarding systems and provide mechanical separation between personnel and hazardous machine zones. Depending on the required visibility, impact resistance, hygiene level and installation method, panels are available in mesh, transparent polycarbonate or solid steel configurations. Troax panels comply with the Machinery Directive 2006/42/EC and EN ISO 14120, making them suitable for automated systems, industrial robots, welding cells and hygienic production environments.

ST20 Mesh Panel

The ST20 mesh panel uses a 19×19 mm steel tube frame combined with a 20×100 mm mesh pattern. It enables clear visibility into the guarded machine area while providing compliant protection. The panel withstands impact loads up to 2100 J in accordance with EN ISO 14120.

• Suitable for standard-risk industrial applications
• Compatible with SmartFix, RapidFix and StrongFix mounting systems
• Installation typically with ≥120 mm safety distance from the hazard

ST30 Mesh Panel

The ST30 is a reinforced variant using a 30×20 mm frame with increased rigidity and higher structural strength. It withstands impact loads up to 6000 J and offers excellent visibility with the same 20×100 mm mesh configuration.

• Designed for high-impact zones and heavy-duty industrial processes
• Ideal for robot cells, high-speed automation and heavy equipment guarding

ST PC Polycarbonate Panel

The ST PC panel provides maximum process visibility through a transparent polycarbonate screen mounted in a steel frame. It eliminates openings that could allow manipulation and can be installed directly at the machine surface, making it suitable for cleanroom and inspection applications.

• Full visual monitoring of the machine process
• High impact resistance and shatter-resistant material
• Prevents bypassing through mesh openings

ST Solid Full-Sheet Steel Panel

The ST Solid panel uses a closed steel plate integrated in a rigid frame. It is designed for environments with sparks, splashes, particulates or the need to block line of sight. It can be mounted close to the machine without compromising safety distances.

• Protection against welding spatter, dust, fluids and process emissions
• No visual access—ideal for guarding sensitive or enclosed machine zones
• Suitable for harsh or demanding production environments

Panel dimensions, materials and finishes

• Standard widths: 200 mm to 1500 mm
• Heights: 750 mm to 2200 mm
• Finishes: RAL 9005 black, RAL 7037 grey, RAL 1018 yellow
• Available in hot-dip galvanized or stainless-steel versions for corrosive or hygienic environments

Panels can be trimmed on-site using dedicated cutting profiles for a precise fit. All variants integrate seamlessly with Troax mounting solutions such as SmartFix, RapidFix and StrongFix.

Fast installation and reconfiguration

Troax guarding panels are fully modular. Panels can be mounted, repositioned or replaced quickly, enabling efficient reconfiguration during production changes, machine upgrades or layout optimisation.
