What Makes Pre Galvanized Unistrut Essential for Modern Construction?

Pre galvanized unistrut channels provide 35-50% faster corrosion resistance compared to post-fabrication galvanizing. With a typical zinc coating of 20-25 µm, these slotted channels withstand 500+ hours in salt spray tests (ASTM B117). Structural integrity remains uncompromised at temperatures ranging from -40°F to 200°F (-40°C to 93°C), making them ideal for both cold storage facilities and industrial plants.

Technical Specifications & Load Capacity

Standard pre galvanized strut channels meet ASTM A1011/A1011M specifications:

• Static load capacity: 4,500 lbs (20 kN) per channel
• Dynamic load rating: 1,800 lbs (8 kN) continuous
• Slot spacing tolerance: ±0.015" (0.38 mm)

FAQS on pre galvanized unistrut

Q: What is pre galvanized unistrut used for?

A: Pre galvanized unistrut is a slotted metal channel system designed for structural support in electrical, mechanical, and construction projects. Its zinc coating provides corrosion resistance, making it ideal for indoor or mildly corrosive environments. Common applications include mounting pipes, conduits, and HVAC systems.

Q: How does pre galvanized strut differ from hot-dipped galvanized strut?

A: Pre galvanized strut is coated with zinc during manufacturing, offering lighter protection suited for dry or low-moisture environments. Hot-dipped galvanized strut undergoes immersion in molten zinc, providing thicker, longer-lasting corrosion resistance for harsh outdoor use. Choose based on exposure conditions.

Q: Can pre galvanised slotted channel be welded?

A: Yes, pre galvanised slotted channel can be welded, but the zinc coating may burn off at weld points. Post-weld, apply zinc-rich paint to restore corrosion protection. Always follow safety guidelines to avoid toxic fumes from heated zinc.

Q: Is pre galvanized unistrut suitable for outdoor applications?

A: Pre galvanized unistrut works outdoors in mild climates with minimal salt or moisture exposure. For coastal or high-humidity areas, hot-dipped galvanized or stainless steel options are recommended. Regular inspections help prolong its lifespan.

Q: What tools are needed to assemble pre galvanized strut systems?

A: Basic tools include a wrench, nuts/bolts, and unistrut-specific fittings like spring nuts or beam clamps. A hole saw or punch may be required for custom modifications. Always wear gloves to protect against sharp edges during installation.
