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
