Shaping & Fixing Details:

Fixing Detail Fixing Accessories

Evergrip gratings can be cut and processed to different shapes and sizes for the most economical use. The cut and processed parts should be sealed with resin to ensure corrosion resistance.

c. Grinding

Cutting Grinding

Standard Clips

There are three kinds of standard clips made of 316 stainless steel used for fixing Evergrip grating: type M, type L and type C.

Type M Type L Type C

Type M Hold Down Clips - designed to fix grating on support structure & prevent it from turning.

Type L Clips - for use in securing grating to support frames.

Type C Clips - applied to connect two adjacent grating bars.

Ideally, Evergrip gratings should be supported on all sides and attached to the supporting framework with either type the ‘M or type ‘L’ hold down clips. A minimum of four clips per side is required for full-size panels. Where panels cannot be supported on all sides, use type ‘C’ end panel clips to connect to the adjacent panels.

Pedestal Support System

In Situ Example

The Evergrip Pedestal support with a screwjack mechanism and integrated spacing tabs adjusts vertically to provide a level installation surface (32mm to 600mm). They are made by injection moulding and are waterproof, durable, and impact resistant.

Adjustable leveling systems

The Evergrip pedestal system is millimetrically adjustable and can be installed in any configuration. The Evergrip type P1 to P12 pedestals, make it possible to adjust the level of the grating platform according to the height of the access thresholds, with continuous adjustment from 32 to 600mm.
