3. 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

4. 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

5. 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

6. 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
