Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of using nylon over rubber or metal sleeves?
A: Nylon offers a superior balance of strength, UV resistance, and chemical resistance. It is lighter than metal, non-corrosive, and more durable than rubber in extreme temperatures and UV exposure. -
Q: Can these sleeves be used in direct sunlight for long periods?
A: Yes, the nylon material is UV-stabilized specifically to withstand prolonged outdoor exposure without significant degradation. -
Q: Are custom sizes available?
A: Absolutely. We can produce sleeves with custom ID, OD, and length according to your drawings or specifications. Minimum order quantities may apply. -
Q: How do I install the sleeve?
A: Installation is straightforward – simply slide the sleeve over the concrete sleeper or push it into the pre-drilled hole. For tight fits, a light tap with a rubber mallet may be used. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15–25 days after order confirmation. Custom sizes may require 20–30 days depending on complexity. -
