draught excluders for bottom of external doors

They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.

Regular maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. With good stability, good corrosion resistance, greatly prolong the service life. More kinds, can be selected according to different uses, making annealing wire device is simple, improve the utilization rate of the device.

Wire mesh first welding after galvanized is through the end of welding and then cold this company to produce wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.

3, a wide variety of specifications, a variety of shapes you choose, both European and American style and today’s popular fashion, full noble and modern beauty.

6, according to the wire diameter thickness to adjust zinc dipping time. Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is the length of the distance between the lead screw on the zinc pot and the ceramic sinking roll. The zinc dipping time of coarse wire diameter should be long, and the zinc dipping time of fine wire diameter should be short.

2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.

Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.

This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.

Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.
