More on steel framed gates
Gate frames are made to size from galvanized tubular steel. Galvanising gives the frames protection from the weather. The steel is welded together for strength. Hinges are also welded on . They pivot on a steel ball bearings and, when lubricated, will give many years of service.
A ring latch provides convenient opening of the gate from either side; rather than the more economical method of having an access hole in the gate, and operating a sliding pad bolt by hand. A pad-bolt is better placed higher up the gate frame, on the inside, to provide a securing mechanism, to which a pad-lock can be attached. Close tolerance locks ,such as deadlocks, are not generally suited to exterior use because of expansion and contraction of exterior timber . Steel to steel would be preferable, but more expensive .
Double gates are usually hung on 125mm square Cypress pine posts, if there is a fence either side to give the posts bracing, otherwise, 100mm square steel posts are an option, but would still require bracing to prevent flexing with the weight of the gates. Driveway gates , which open inwards towards a rising driveway, require special rising hinges to allow the bottom of the gate to clear the roadway. Proprietory hinges for this purpose are expensive, although a cheaper custom made product can be used to overcome the problem, depending on the steepness of the driveway.
Rollable driveway gates on tracks can be motorized, with a choice of 240 volt mains power, 12 or 24 volt low voltage , or even solar power, depending on the situation. Do enquire about gate repairs, e.g. rusted hinges, broken latches etc, because often, gates with steel componentry can easily be repaired and not scrapped.
