Another school job just sprung to mind , after taking over this set of gates we found a number of safety issues that have been resolved and this wonderful example of a control panel , as you can see the re fitted version is somewhat tidier.

We don’t install wooden gates anymore. I took the decision to stop installing wooden gates and posts a couple of years ago , no matter how good the quality of the wood or the joinery shop making the gates , there’s always something going to happen with them, clients don’t maintain them , then they move , swell , rot , yes they look nice at the start but the cracks show after a while.

Another aluminium gate installed today as you can see from the rotten pile of wood on the side we didn’t even have to remove the old gate , that fell off 3 months ago.

New gate has been powder coated to the cilents exact colour to match the walls and doors when the painters start next week.

Factory fitted lock and strike interfaced with existing intercom.

Not all gates are created equal, in fact some security products can cause a false sense of security.

This customer had a bar gate on their front door , they expected it to be secure unfortunately a small crow bar flexed the lightweight construction open and lead to a burglary. We were tasked with replacing it with something more secure and safer in the event of a fire

Full box section frame and gate , fully welded seams (no quick tack welds here like I see on some gates) , clad with solid and perforated sheet to allow visibility but no access to the inside thumbturn.
