For heavy-duty applications, prioritize UHMWPE (Ultra-High Molecular Weight Polyethylene) or HDPE (High-Density Polyethylene). UHMWPE is superior due to its high load-bearing capacity, self-lubricating properties, and exceptional impact resistance. Ensure the material has a molecular weight of at least 3 to 5 million g/mol to prevent cracking under extreme pressure. For metallic outrigger components, verify the use of high-tensile strength steel (e.g., Q345B or Q960) with anti-corrosion coatings.
