What does hardware building materials include, what does hardware building materials include

1. Hardware material products are usually divided into two categories: large hardware and small hardware. 2. Large hardware generally refers to metal plates, pipes, profiles, bars and wires; 3. Small hardware mainly includes coated plates (such as white iron sheets), coated wires (such as iron wires), and various small standards.

Hardware and building materials include: steel plates, flat iron, channel iron, steel bars, I-beams, universal angle steel, building hardware, white iron sheets, iron wires, wire cutters, lock nails, steel materials, mechanical parts, non-ferrous metal materials, auxiliary tools, profiles, bars, plates, wires, etc. Hardware building materials refers to gold, silver, copper, iron, tin five metal materials, it is the mother of industry, the foundation of national defense, hardware building materials products, usually only divided into two categories: large hardware building materials and small hardware building materials.

Small hardware and building materials are divided into building hardware, white iron sheets, lock nails, iron wires, steel wire mesh, steel wire shears, household hardware, various tools and building materials, etc. In terms of the nature and use of hardware and building materials, it should be divided into eight categories: iron and steel materials, non-ferrous metal materials, mechanical parts, transmission equipment, auxiliary tools, work tools, building hardware, and household hardware.

In our daily life, it is inseparable from building materials and hardware. We can divide hardware into hardware parts, daily hardware, hardware tools, building hardware and security supplies for several different use categories. The building hardware in the hardware and electromechanical is the general term for the metal and non-metal products and accessories installed in the building or structure.

It generally has a dual effect of practicality and decoration.

Automatic doors and gated hardware building materials: all kinds of automatic doors, gated hardware systems and accessories, access control electronic systems and other overall kitchens or overall home furnishings and materials and related equipment: overall cabinets, materials, washing sinks, faucets, kitchen pendants, kitchen stoves, kitchen appliances and equipment, wall cabinets, sliding doors, partitions, etc.

We have to use a lot of decoration materials when decorating the house, hardware products are not only some parts of the interior, some pendants in the kitchen, etc., the application of door and window hardware is also very extensive, in the structure of doors and windows, the hardware accessories of doors and windows are also widely used. In this way, we will not have any trouble decorating. Then let's introduce it to youHardware and building materialsWhat is included, install door and window hardware building materials accessories installation.

1. What does hardware and building materials include.

1. Hardware material products are usually divided into two categories: large hardware and small hardware.

2. Large hardware generally refers to metal plates, pipes, profiles, bars and wires;

3. Small hardware mainly includes coated plates (such as white iron sheets), coated wires (such as iron wires), various small standard parts (such as fastening screws), non-standard parts (such as wood screws) and various small tools (such as screwdrivers) and so on.

Second, the installation of door and window hardware accessories.

1. Installation of the handle: The installation of the handle should be ergonomic and easy to use. When installing, the handles of the same wardrobe must be neat and consistent. The length of the screws should match the thickness of the windows and doors. When using an electric drill to open a hole, the hole size should be consistent with the diameter of the screw.

2. Hinge installation: generally the door is installed with two hinges with a length of 100mm, if it is a solid door or a concave-convex modeling door, three hinges must be used, or two hinges with a length of 125mm must be installed.

3. Installation of locks: After the door lock is installed, the handle should be between 900-1000mm from the ground. When installing, install the lock body and the deadbolt first, make the deadbolt plate flush with the door edge, close the door, set the position of the locking plate, and then install the locking plate, and ensure that the locking plate is flush with the edge of the door sleeve.

4. When installing hardware accessories, you should first drill a hole slightly smaller than the diameter of the screw on the frame and fan rod, and then screw it in with the self-tapping screws of supporting Zhaoheng, and it is strictly forbidden to drive the screws directly with a hammer. The door lock installation should be carried out after the door hinge is installed.

The above article is to introduce to you what hardware building materials include, the installation of hardware and building materials accessories for the number of windows in the state. Hope the provision is helpful to you. For so many products, no matter how you buy, you must choose a good brand to get good quality.

Your reading is the driving force.

Building materials and hardware mainly include five metal materials: gold, silver, copper, iron and tin.

1. Gold. Gold is a transition metal that, when dissolved, can form trivalent and monovalent positive ions. Gold does not react chemically with most chemicals, but can be attacked by chlorine, fluorine, aqua regia and cyanide.

Gold can be dissolved by mercury to form amalgam; Nitric acid, which dissolves silver and alkali metals, cannot dissolve gold. The above two properties have become the basis of the first refining technology, which are respectively called "silver and gold separation method" and "gold and silver separation method".

2. Silver. Silver is a type of transition metal. Chemical symbol AG.

Silver is one of the metals known and utilized since ancient times, and it is an important one. Natural silver is mostly alloyed with gold, mercury, antimony, copper, or platinum, and natural gold is almost always alloyed with a small amount of silver. The ancient amber gold known in China, known as electrum in English, is a natural gold-silver alloy containing about 20% silver.

3. Copper. Copper is a transition element, the chemical symbol Cu, English copper, atomic number 29. Pure copper is a soft metal, the surface is reddish-orange with metallic luster when it is first cut, and the elemental color is purple-red.

It can also be used as a building material and can be composed of many alloys. Copper was one of the first metals used by humans. As early as prehistoric times, people began to mine open-pit copper and use the obtained copper to make **, tools and other utensils, and the use of copper had a profound impact on the progress of early human civilization.

As it is. Copper building structures can be corroded to produce patina (basic copper carbonate). The decorative arts mainly used metallic copper and copper-containing pigments. The amount of copper in the earth's crust is about, and in individual copper deposits, the copper content can reach 3% to 5%.

Most of the copper in nature exists as a compound, that is, copper ore.

4. Iron. Iron is widely distributed in life, and the slag is widely distributed, ranking fourth in the earth's crust content. Pure iron is a flexible and malleable silvery-white metal, used to make the core of generators and motors, iron and its compounds are also used to make magnets, drugs, inks, pigments, abrasives, etc., is one of the "ferrous metals" in the industry, iron is called "ferrous metal" because the surface of iron is often covered with a layer of black main components.

The main iron ores used are: hematite, magnetite, siderite, pyrite.

5. Tin. Tin, a metallic element, is a metallic element with a silvery-white luster with a low melting point, which is divalent or tetravalent within the compound, is not oxidized by air, and exists mainly in the form of dioxide and various sulfides. Element symbol sn.

Tin is one of the famous "hardware" - gold, silver, copper, iron, and tin. Tin is malleable at room temperature. Especially at 100 °C, it is very malleable and can be retracted to form a very thin tin foil.

Usually, people use tin foil to wrap cigarettes and candies to protect them from moisture.
