Abstract
An intruder resistant screen providing improved strength. The improved intruder resistant screen comprises a frame, a woven wire intruder resistant mesh covering an opening enclosed by the frame, a plurality of clamp elements engaging with frame members to hold the mesh by a leveraged clamping action and at least one fastener holding each clamping member to the frame member. Each fastener has a drilling portion, a shank portion, a head and a thread. The frame comprises multiple frame members joined by corner stakes and there are two or more clamp elements engaging each frame member.

An improved intruder resistant screen comprising:
- a frame comprising multiple frame members joined by corner stakes;
- a woven wire intruder resistant mesh covering an opening enclosed by the frame;
- a plurality of clamp elements made of carbon fibre reinforced polymer engaging with the frame members to hold the mesh by a leveraged clamping action;
- and
- at least one fastener holding each clamp element to the frame member;
- wherein there are two or more clamp elements engaging each frame member;
- and
- wherein each fastener has a drilling portion, a shank portion, a head and a thread.
A method of assembling an improved intruder resistant screen including the steps of:
- assembling a frame by fixing corner stakes in each end of a channel of a frame member such that adjacent frame members are held abutting by a corner stake;
- locating a woven wire intruder resistant mesh within an opening enclosed by the frame;
- engaging a plurality of carbon fibre reinforced polymer clamp elements with the frame members so as to apply leveraged clamping to the mesh, there being two or more clamp elements engaging each frame member;
- and
- screwing a self-drilling screw into the frame member through a countersunk hole formed in the carbon fibre reinforced polymer clamping element.
