Small and medium-sized cat cage, dog cage and fence are mostly pure wire welding, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage has to withstand more force.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

After special finishing operations, you may cut the profiles into shorter lengths depending on the actual dimensions of the windows and doors. While at it, you may use special devices to clamp the profiles, cut and transfer them to a conveyor.

It will come as no surprise to learn that modern windows are primarily intended to be ‘warm’. This means that they are not supposed to allow warm air to escape from the house. This parameter is described by the heat transfer coefficient Uw, which gives us the answer to the question of how much heat escapes through the window due to the difference in external and internal temperatures.

    For those seeking to add a touch of flair to their architectural designs, cast iron collars offer a perfect solution. These ornate embellishments lend a sense of intricacy and charm to staircases, balconies, and other structural elements, creating a cohesive look that exudes style and sophistication.

The most common component of contemporary wrought iron fences is the tubing made of iron or steel. The tubes are worked into forms by machines, and the manufacturers also utilize devices to produce the decoration traditionally used with a wrought iron fence. The lines are welded together to form wall panels, resulting in a robust iron fence.

we typically use one-inch square posts core drilled and set in hydraulic cement when we’re installing railings. For fencing, we use heavy duty steel posts that we galvanize, prime, and paint, set into concrete footings. The environment of your property may influence preparations as well: for instance, galvanizing is particularly important if the structure is near water.

A last and even more important, additional advantage of polyamide is the excellent thermal insulation. While aluminium scores much less well than wood and PVC in that area, it performs at least as well in terms of U_f value thanks to the polyamide strips (which insulate 500x better than aluminium).

These aluminium window designs rely on suitable framing and significant expertise by the installer. Only maximum glass sizes determine the sizes possible. Crucially, there are more technical or structural considerations over and above standard window designs, such as wind deflection.
