Detailed Product Description
Elevator Guide Rails - Frequently Asked Questions
What difference is there between cold-drawn and planed guide rails? The process for cold-drawn involves stretching the material thus modifying its structure. Planing involves machining the guide rail by stripping the edgings.
Why can't the cold-drawn guide rails be used at speeds over 1.6 m/sec? Because the cold-drawn process produces short bends caused by the variations in the raw material thickness rolled along the section. These bends make the lateral acceleration rates high.
