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.


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.

Decorative Durability

Rigidized® Metals' Rigi-Grip® tube in stainless steel is the ideal choice for many high traffic applications. The texture in our products provides added strength and durability with its ability to hide scratches, dents and dings. This reduces maintenance costs, making our products more sustainable and longer-lasting while increasing aesthetic appeal.

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.
