ALPAR Wysięgnik OC W20 galvanised support arm 0.5×0.5 m

ALPAR Wysięgnik OC W20 galvanised support arm 0.5×0.5 m is a compact cantilever bracket made from hot-dip galvanised steel. It is intended to provide a corrosion-resistant mounting point for fixtures and equipment in outdoor or industrial environments. The simple square-section arm and robust galvanised finish make it suitable where a short, sturdy projection is required to support lights, signs, antennas or similar devices.

Advantages

The hot-dip galvanised construction delivers long-term corrosion protection without the need for additional surface treatment, reducing maintenance in exposed conditions. Its compact 0.5×0.5 m dimensions allow installation on poles, walls or masts where space is limited while still providing a stable cantilever for mounted equipment. The straightforward design facilitates quick mounting and alignment with standard fasteners.

Suitable for

• Mounting outdoor luminaires and floodlights
• Supporting small signage or advertising panels
• Fixing radio or TV antennas and short aerials
• Providing a projection point for sensors, cameras or small access points

When it may not be suitable

This support arm is designed for short projections and moderate loads; it is not intended for heavy structural loads or long-span cantilevers. For large signage, heavy fixtures or installations subject to high wind loads, a larger or engineered mounting solution should be selected and structural calculations performed.

Key specifications

• Material: hot-dip galvanised steel for corrosion resistance
• Arm projection: 0.5 × 0.5 m square section
• Type: cantilever support arm for external mounting
• Surface finish: galvanised (zinc coating) for outdoor durability

How to use

Choose a suitable mounting surface such as a pole, mast or reinforced wall. Align the support arm so the projection faces the required direction and mark the fixing points. Use appropriate stainless or zinc-coated fasteners and, where necessary, washers and nuts sized for the mounting holes. Tighten fasteners to recommended torque for the chosen hardware and confirm the assembly is level and secure. Attach the fixture to the free end of the arm using compatible brackets or clamps, and verify stability under expected load and environmental conditions.

What to consider before purchase

• Confirm the weight and wind load of the device to be mounted and verify compatibility with a 0.5 m projection
• Check mounting surface strength and select appropriate fasteners for steel or concrete substrates
• Consider local exposure to salt spray or aggressive environments and whether additional protection or thicker material is required

Usage recommendations

For outdoor lighting or antenna installations, inspect the galvanised coating periodically and tighten fasteners after initial weather exposure. If mounting heavy or large items, consult a structural specialist to ensure safe installation and compliance with local regulations.
