When you invest in a wrought iron fence, you’re not just putting up a boundary. You’re making a statement, safeguarding your property, and elevating your home’s value in a way that only this timeless material can.
Nevertheless, it can range from +/- 0.2mm to +/- 0.5mm as standard but still subject to improvement if need be.


What are aluminum window extrusion profiles made of?
Speaking from personal experience as a welder, steel is a lot easier to work with than iron. If someone manages to break a piece of steel (which isn’t easy), repairing it is a simple matter of properly positioning the pieces and welding them together. In contrast, repairing a cracked or damaged piece of iron means heating the whole piece back up to nearly molten temperatures, then carefully welding it in stages--with pauses to reheat the piece--while sometimes giving it a whack with a hammer and hoping you don’t hear the tell-tale ping of a crack forming somewhere else. Iron is a finicky material.
Aluminum profiles are metal materials. Aluminum add various metal elements to make various alloys, which have advantages that other alloy profiles cannot match. Aluminum alloys has light weight and high strength, and can be extruded into a variety of complex cross-section profiles meeting the requirements of door and window design for various new sections.
Aluminum is ideal for contemporary windows and doors framing since the material is strong and bears a substantially large amount of weight.
3. Rubber Wheels Rubber wheels are an excellent choice for sliding doors that require quiet operation. They provide a cushioned glide and are gentle on the track, reducing wear. However, rubber may degrade faster compared to harder materials, especially when exposed to UV rays or extreme temperatures.
Security Features
The stakes are high, and with both materials boasting their own sets of advantages, the decision-making process can feel overwhelming. Below, we’ll compare and contrast these two choices against the most important criteria: aesthetics, cost, durability, security, and more.
In essence, where tighter tolerances are required, the manufacturer may work on the standards as set out in BS EN 12020.
