FAQ

Q: What is the material of the elevator guide rails?

A: The tensile strength of the raw material used (steel) shall be at least 370 N/mm2 and not more than 520 N/mm2. For this purpose, it is recommended to use steel grade E 235 B for cold-drawn guide rails and steel grade E 275 B for machined guides. In China we use steel grade Q235.

Q: What do the rails of A, B, and BE represent?

A: Guide rails may be cold drawn or machined. In the International Standard, the manufacturing process for each type of guide is indicated by the symbol /A for “cold drawn”, the symbol /B for “machined”, and the symbol /BE for “machined high quality”.

Q: Why are the guide rails 5 meters long?

A: The guide rails are 5 meters long because it is the appropriate manufacturing length and allows the parameters for straightening to be checked properly. We can supply lengths shorter than 5 meters for each one.

Q: Do the guide rails have any surface treatment?

A: No, the guide rails do not have surface treatments. On cold-drawn guide rails the cold-drawn process modifies the mechanical features of the material.

Q: What is the difference between cold-drawn guide rails and machined guide rails?

A: The process for cold-drawn involves stretching the material thus modifying its structure. Planing involves machining the guide rail by stripping the edgings.

Q: How to name guide rails?

A: The naming of guide rails varies by country. Some name guide rails based on the width of their guiding aspect, such as T9 and T16. Others name them according to their weight, like 8LB and 12LB. However, we primarily name guide rails based on the width of their bottom, for example: T70 and T50.

Q: Do we offer samples?

A: If your demand is just a few, then we can offer without charge, while if the quantity is more, then we will charge considering your situation. 

Q: What's the way of delivery and delivery date?

A: The delivery date depends on the quantity of the goods. Usually, it takes 10 days to prepare one small container. And concerning the way of delivery, we’d like to TT payment. If the policy in your country allows only LC or other way, then we can discuss.
