A Better Grip

Rigidized® Metals' Rigi-Grip® tubing is perfect for railings, grab bars and transportation holds, in order to limit and prevent accidental injury. The textured surface is up to six times more grip-able than ordinary handrail. With standard diameters of 1.25" and 1.5" they can be used for ADA-compliant gripping rails. The Trim-Tex 8" wide strip is used to create both rail and other shapes. Rigidized® Metals supplies textured tubes to fabricators of handrail systems.

A Commanding Grip

Demanding applications call for Rigidized® Metals' Rigi-Grip® tube in stainless steel construction for corrosive environments (like salt water), and enhanced grip in wet environments.



Grip Comparison Guide

The tables below compare the friction and grip-ability of selected samples. Specimens were tested in dry, wet and oiled conditions. Independently tested material and devices are not to ASTM specification. Testing was based on ASTM G115-98 (testing coefficient of friction), ASTM A947M-95 (specs for textured steel), and ASTM A554 (standards for manufactured tubing). The data is provided as a selection guide and is not intended to substitute for certified testing.
