Frequently Asked Questions
It is the length of the gap that needs to be closed. Measure the length at various heights. As walls and posts are seldom straight, always supply the shortest measurement on your quote request. The gate manufacturer will consider the hinges and closing mechanisms and adjust the gate frame accordingly.
Measure the height of the opening that you want to close and supply that measurement. The gate manufacturer will always allow for 50mm from ground level and adjust the gate frame accordingly. If the gate opening is framed at the top, mention that to the gate manufacturer.
Make sure the gate height is measured from the highest point. Otherwise, the frame will not fit. Also consider the swing path of the gate and see that the highest point on the ground does not impede the swing path of the gate.
Many elements. The quality and diameter of the steel. Steel frames should not be less than 2mm – watch out as this is the element that you cannot observe. The quality of the welding and rust protection or galvanizing. The quality, thickness, and coating of the components
like hinges and pad bolts.
It has to be fit for purpose first. Consider the traffic and how often it will be used.
Some tips are: Make sure your hinges line up vertically. Make sure the hinges are attached to a post that is vertical. Allow for 50mm on the bottom of the gate to swing freely. Adjust the hinge bolts in or out to move the gate closer or further from the closing mechanism. There are many other things to consider, but most of it is fairly easy. Do not undertake the job if you are not reasonably confident that you can complete it to your expected standard.
Hinge bolts are great for industrial gates. It is a round steel bar that has a round eye at the one end and then a 300mm straight part which is threaded with two nuts. The eye curls around the gate frame. The gate frame rotates inside the eye of the hinge bolt. The straight threaded end goes through a hole in a post with two nuts securing it. The bolts can be adjusted in or out to line up the gate. When attached to a wall the hinge bolts are shortened and then chemically bonded inside drilled holes in the wall.
A galvanized gate is mostly a gate made from pre-galvanized steel. Cold galvanizing and a top layer of silver paint finishes the welding and cut distress points. This method allows for a more cost-effective galvanized gate and should last reasonably long. If you require better rust proofing, you will have to consider a hot dipped galvanized gate.
A hot dipped galvanized gate is manufactured from untreated steel and is then sent to a hot dipped galvanized plant. There it is dipped in molten zinc that covers the entire gate inside and out. This is the ultimate in rust proofing.
Consider the following elements for a top-notch industrial sliding gate: Work with a reputable company with lots of experience. They may be more expensive but will not cut corners. Great welding and using A grade steel. Overengineer the track steel as this is the part that mostly gives you trouble down the line. Inspect the wheel housing – great manufacturers rather use their own upgraded housing. Delivery on time and not overpromising.
