Pultrusion is a manufacturing process used to create reinforced plastic shapes by pulling fibers through a resin bath and then through a heated die. This technique results in strong, durable materials ideal for constructing various products, including ladders.

- Continuous roll of reinforced fibers/woven fiber mat
- Tension roller
- Resin impregnator
- Resin soaked fiber
- Die and heat source
- Pull mechanism
- Finished hardened fiber reinforced polymer
Key Benefits:
- Improved Strength: Offers superior durability and long-lasting performance.
- Lightweight: Easier to handle and transport due to reduced weight.
- Corrosion Resistance: Pultruded materials resist corrosion well, making them ideal for outdoor and industrial use.
Applications:
- Used to create lightweight yet sturdy ladders that can withstand significant loads and harsh conditions.
- Ideal for producing high-strength components in construction and industrial applications.
OSHA Compliance for Pultruded Ladders:
Key OSHA guidelines for Pultruded Ladders:
- Load Capacity: Ensure that pultruded ladders meet or exceed OSHA’s load capacity requirements for the intended use.
- Material Standards: Follow OSHA guidelines for the materials used in ladder construction to ensure safety and durability.
- Regular Inspections: Conduct regular inspections of pultruded ladders to maintain compliance and ensure ongoing safety.
