FAQ

1. This cushion is made of rubber. How long will it last in harsh job site conditions (mud, grit, oil)? Won't it age and crack quickly?

We fully understand the extreme conditions of construction sites. Therefore, our products are made from high-strength, wear-resistant, oil-resistant special synthetic rubber, compounded with UV and ozone resistance additives. They offer excellent resistance to oil, mud, and weathering, and can withstand continuous impact and extreme temperature swings. Under normal use, their lifespan typically far exceeds that of ordinary rubber parts. To maximize life, we recommend periodically cleaning off heavy accumulations of mud and grit and avoiding continuous severe abrasion with sharp, hard objects.
2.Are other colors available besides black? Can you customize sizes?

Color: The standard product is black due to the carbon black that enhances wear and aging resistance. For special needs (e.g., to match corporate fleet colors), we can explore color customization, though a minimum order quantity may apply.
Customization: We support non-standard size customization. If you have special machinery or modification projects requiring uniquely shaped cushions, please provide detailed drawings or samples. We can undertake mold-making for custom production to meet your specific construction machinery protection needs.
The specific installation time depends on the structure of the dock, and it usually takes 1-2 days to complete.
