The factors that should be considered when purchasing plastic steel windows
1. To select profiles, first understand the pvc profile that is used for the plastic window.
PVC profiles are the decisive factors for the quality and grade of plastic steel windows. A good PVC profile should be a reasonably designed multi-cavity, wall thickness, formula containing anti-aging, anti-ultraviolet auxiliaries, from the appearance point of view should be smooth surface, color blue and white . The middle and low profile is white and yellow, this color is poor in sun protection ability, after use a few years will become more yellow until aging, deformation, embrittlement, so the thickness of the profile should be greater than 2.5 mm, the inner cavity is The profile of the three-cavity structure (with a closed drainage chamber and isolation chamber, reinforcement chamber) ensures that the window is not deformed for decades.
In addition, such profiles are not easy to change color and are not easy to age.
2. Pay attention to surface quality. The plastic profile of the door and window surface is blue-white or ivory white. It is clean, smooth and smooth. There are no scratches or bumps on the large surface, and there is no welding at the welding port. fracture. The surface of the good quality steel doors and windows should have a protective film, and the user should tear off the protective film before use.
3. For houses with high outdoor noise, it is best to use plastic windows equipped with insulating glass, which has excellent sealing and sound insulation.
4. When the steel window is closed, the push-pull steel window between the fan and frame should slide freely and without dust.
5. The steel window frame should have a steel liner sound soft glass is installed flat and solid and does not directly contact the profile, if it is double-glazed, there should be no dust and moisture in the sandwich layer, and the switch components are tight and flexible.
How to modify, use solid wood door
Solid wood doors are part of high-end luxury doors and windows, and can be made of red spring wood, Thai teak wood or rosewood wood. Commodity solid wood door specifications are 80 cm × 190 cm, 80 cm × 100 cm, 90 cm × 100 mm.
The price of each door ranges from 1,500 to 3,000 yuan, and high-quality teak doors are as high as 3,000 to 4,000 yuan.
Innovative products, as well as steel doors. Framed with steel, the skin is inlaid with plastic and the appearance is rather hardwood varnish. Can be made of double doors, and attached to the door frame, each about 500-800 yuan, can also be measured in accordance with the door size specifications accurately measured.
Plastic steel door has the characteristics of heat preservation, heat insulation, noise elimination, sound absorption, flame retardant, etc. It is economical and practical, and its appearance is gorgeous.
How to buy a security door The key to buy a security door is strong. There are three points for reference:
1, the material should be thick. The thickness of the pipe is generally not less than 1.2 mm, the surface finish of the steel management body is high, there is no rough blistering, and the thick steel pipes are sounded with good sound quality and feel steady.
2, the structure should be reasonable. The anti-theft door with the door frame is more secure and easy to install in the summer. The distance between the gate fence steel pipe is not more than 6 cm (the best hand does not come in).
3, the lock should be selected to lock the third tongue lock multi-security anti-theft pin, indoor and outdoor can be opened or locked, and install the door on the door to protect the iron plate, so that keyless persons are difficult to shake.
What are the characteristics of aluminum alloy doors and windows:

4, strong corrosion resistance: aluminum Taiwan gold oxide layer does not fade. No fall off, no paint, easy maintenance, no maintenance.
Solid wood and solid wood composite door
A. Solid wood door.
According to the material there are two kinds of wood and logs. The wood properties are stable and not easily deformed. It is made directly after sawing the wood. The main points of purchase are water content less than 12%, fine processing, no obvious wink, no burr, accurate processing dimensions, and complete lines. The characteristics are steady and elegant, but the price is relatively expensive. The relative stability of logs is relatively poor and they are easily deformed.
2. Solid wood composite door.
The characteristic is that the door frame is made of high-quality solid wood, and all of them are heat-treated, invariable, and do not crack; the facade is made of decorative panels.
1) Mosaic Decoration Door facade The veneer is made with advanced mosaic technology and is made of imported high-strength integrated glue. Honeycomb insulation board inside the door, play a good sound insulation effect;
2) The solid core decorative door leaf is filled with heat-insulating and fire-retardant materials and processed. Can set small pieces of glass, rich shape, performance and solid wood doors, but the price is much cheaper than solid wood doors, and fire retardant;
3) The plywood decorative door leaf is a keel, and the outer plywood is mainly a plywood. The advantages are light weight and low price.
Three. Molded door
Molded door facade is a MDF pressed by a mould. The door leaf consists of keel and sound insulation paper. It is characterized by good stability, no deformation, no shrinkage, and relatively low price. However, due to the mold repression, the choice of colors and types are relatively small.
IV. Closet door
The closet door is a kind of decorative door that is based on the wall as a cabinet body, and utilizes the matching hardware accessories such as a pulley and a slide rail to push and pull. Its characteristics are mainly to make full use of space, beautiful and generous shapes.
V. Plastic doors and windows
Plastic steel doors and windows are based on polyvinyl chloride (pvc) and chlorinated polyethylene blended resin as the main body, plus a certain percentage of additives, after extrusion processing. In order to increase the rigidity of the profiles, steel liners (ribs) that increase the bending resistance are filled in the inner cavity of the plastic profiles, and then the doors and windows are made by cutting, drilling, welding, and the like.
It not only has the characteristics of plastic products, but also the physical, chemical properties, anti-aging ability is greatly improved, acid, alkali, corrosion resistance, dust, fire-retardant self-extinguishing, high strength, non-deformation, color tone and other advantages.
6. Security door
The materials used for qualified anti-theft security doors are all in line with national standards. The thickness of the steel security door frames should not be less than 2 mm. The front and rear panels of the door panels generally have a plate thickness of 0.8-1 mm. Skeleton and reinforcing plate, and play a certain anti-vandalism performance, and can meet the anti-theft level required by national standards.
The most important component of the security door is the anti-theft lock. The performance of the anti-theft lock is directly related to the security of the door. The security door generally uses mechanical and electronic locks.
When the anti-theft lock is selected, it should be noted that the product must be certified by the national authorized authority.
The anti-theft lock should have the functions of anti-drilling, anti-saw, anti-slug, anti-pull, anti-impact and anti-technical opening.
Construction of doors and windows points 1. Pay attention to the location of the installation, measure the size of the doors and windows;
2. The upper side of the door cover is leveled and the door points are reserved evenly. The state provides 2.5-3mm on each side, 2mm on the upper side, and 5mm-1cm on the lower side. It is recommended that the installation time be the first time before the coating is applied.
3. Leave a spacing of about 2.5 centimeters between the wall when installing the door pocket;
4 pay attention to the use of expansion bolts, pay attention to the amount of plastic, while doing a good outside waterproofing;
5. Pay attention to the protection of the door when installing, so as not to damage the paint.
common problem
1. Doors and windows may leak, it is recommended to use glue or waterproof.
2. Because the solid wood door has a high moisture content requirement, a slight deformation or cracking of the door body will occur after about one and a half years of use, and the manufacturer can be contacted for repair.
3. As the indoor air is overheated, it will cause bubble gum to evaporate and the door sleeve will shrink, which will cause the door body to not close. Contact the manufacturer to re-apply the glue;
4. The composite door is prone to cracks in the pressure line, mainly due to changes in the indoor temperature and humidity, re-painting putty;
5. The compound gate should be evenly coated in the process of processing, and the pressure of the machine will not be enough to cause blistering;
6. Doors and windows should pay attention to the maintenance of hardware during use.

Shear Beam Load Cells are widely used where operators need to measure compressive forces. The core component of a shear beam load cell is a spring element. This element is a piece of metal that is elastically deformed under load and recovers the moment the load is removed.
The (single-ended) shear beam is designed for low profile scale and process applications. The shear beam capacities are from 100kg to 50t. One end of the shear beam contains the mounting holes while the opposite end is where the cell is loaded. The load cell should be mounted on a flat smooth surface with high-strength hardened bolts. The larger shear beam cells have more than two mounting holes to accommodate extra bolts to keep the hardware from stretching under stress load.
Shear beams are available of nickel-plated alloy steel or stainless steel for use in harsh environments.Load Cell Central,Shear Beam Load Cells,Larger Shear Beam Cells,Load Cell Measure Compressive Forces
