HOW GOOD ARE YOUR SECURITY GATES? Herman de Meyer of Santam says that sometimes the steel used to make off-the-shelf security gates is not the right quality or weight and, even if you buy the best gate, how it is installed can make or break its effectiveness. Here is a list of common gate weaknesses. TRELLIS-TYPE GATES• The steel isn’t strong and the welding is poor and only on one side. • The hinges are too light and are attached to the wall with wooden screws and screw plugs instead of rawl plugs.• Too large an opening is left on the side of the gate. • The locks are of a poor quality and the lock pins are not protected and can be sawn off. • Bolt holes are drilled too close to the edge of the wall.SLIDING GATES:• The steel is too heavy, which weakens the rivets. • Locks and lock pins can be broken easily. What to look out for when buying a gate:De Meyer says the frame of a lattice-type gate must be made of at least 25mm square pipe and the bars must be at least 12 mm thick.“The bars must go through the horizontal square pipe and then welded. “The hinges must be of the pin type and must be welded to the gate and the hinge plate or fixed frame. Flat hinges are not strong enough.“Sliding gates must be fixed to the inside of the door to offer the most resistance. And hire an expert to install your gates,” De Meyer said. -Supplied.
