1. Cutting Tools

Cutting Tool Options

Jigsaw (Bosch T341HM tungsten tipped blade only) Used for simple straight cuts, radius edges and for intricate shapes Useful for notching out sections A proficient Jigsaw operator is capable of absolute precision

Circular Saw (diamond tipped blade only) For cuts that exceed 1 metre and provides a perfect straight line cut Usually quicker than using a jigsaw but limited to cuts in one direction at a time Can be sourced from Dewalt, Bosch or Hilti etc A proficient Circular Saw operator is capable of absolute precision

Angle Grinder (metal blade only) A compromise between Jigsaws and Circular Saws Metal blades will wear more quickly than diamond tipped type but cut just as quickly Smaller blades & lack of cutter guide mean that accuracy relies on operator precision A proficient Angle Grinder operator is capable of executing accurate cuts

2. Fixing Tools

Standard Fixing Tool Options

Drills Used for creating the fixing points in the structure beneath the grating UK specifications require an M8 fixing so an 8mm or 9mm hole is drilled Drill can also used with attachments such as Hex (Allen) key tool or a

socket to the correct diameter of the fixing bolt to enable rapid tightening of the fixings

Spanners Standard spanners can be selected to suit the relevant fixing bolt Spanner allows the operator to tighten all fixings

3. Fixing Systems

Square Recess Clip (& Nut, Bolt & Washer) Involves drilling the supporting structure and fixing panel down with nut & bolt This method requires access underneath the grating panel Average installation speeds (Recommended for Dura Tread products)

Square Recess Clip (& Self Drilling, Self Tapping Bi-Metallic Screw) Is the easiest fixing system Is most suited to projects when fixing to a metal structure Designed to self drill through the steel and cut its own thread Results in rapid installation speeds Does not require access under the grating panel Clamping System A J-Clamp assembly that clamps to the structure beneath the grating This method also requires access underneath the grating panel

Screw Fixing Traditional screws can be used for installation onto a wooden structure Can be used in conjunction with a standard clip (see above) and a variety of

wood Screws dependant on the thickness of grating and the structure beneath

4. Off-Shore Cutting & Installation

Fibreglass Grating panels can be cut on-site in an off-shore environment using any of the recommended hand tools previously listed

It is possible to choose from a number of international power tool manufacturers such as Dewalt, Bosch or Hilti

These suppliers tend to have excellent warranty and customer support facilities

We regularly use battery powered tools on installations in the UK where extra mobility is required, this may be a suitable option in on off-shore environment out of range of a power supply

It is essential to keep a large stock of the appropriate blades to suit each power tool
