Boilers making etc.

 

Packaging & Delivery

Packaging Details: The Steel Flat Bars are packed in bundles and loaded in 20 feet/40 feet container, or shipped by bulk cargo ,also we can do as customer's requirements.

Delivery Details:30~45 days upon the receipt of buyer payment by T.T. or L/C.

Production

The Carbon Steel Flat Bar is made through three processes:

1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.

2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.

3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length.

Q:The steel and wood preservative in the flower is how to connect
Or with the aid of angle steel, angle steel and steel welding, wood preservative and angle connected by bolts.
Q:The working principle of steel punching machine
Imported PLC control system, industrial color LCD touch screen AC servo motor and driver, imported linear guide rail and fine ball screw, universal ball or brush board, work table and other high-end configuration;
Q:How the two square welded T shape angle and turning angle, how to improve the speed and quality?
You can't weld well without using tools, and it can't be welded with high quality. If the site is large and batch welded, you can use wood as a standard corner frame (quite a template). ), if the amount is small, you can buy a wooden triangle plate, steel square to live, post welding,
Q:You need to light steel keel wall square steel
Needed. The material of the light steel keel partition wall is galvanized iron plate, the pressed keel and the gypsum board (or calcium silicate board), its merit is the light weight, easy to walk the electric wire tube, the construction is quick. But the fire is not good, it is dry work. The cost is higher.
Q:The difference between square and square.
Square steel, solid, of bars. Generally processed by hot rolling, deep processing can be made into round steel, anchor bolts and so on. Used to make tracks.Square pipe, hollow, belong to pipe material. There are rounded, the quality should be lighter than steel. Small diameter is generally cold-rolled, large diameter welding generally spell. Used to make structures.
Q:The water was poured into the square on how to prevent rust after treatment
Of course, all can be cloth, face sassafras. After the surface has been cleaned, it is better to put rust on the inside and outside surfaces and store them.Then is the steel material after storage should always check, if there is corrosion, corrosion layer should be removed.Finally, the corrosion of the more serious square steel, rust should not be long-term storage, should be used as soon as possible.
Q:How to ensure the steel paint off paint
Ensure the paint off square paint method:1, the steel brush must do the clean work before painting, there is no guarantee the steel rust or grease, the steel surface cleaning is the basis to ensure the paint off.2, must use special metal paint finishing of polyester type steel, to ensure no paint brush.3, paint to ensure that the film extended evenly.
Q:It can be used as the steel electrical equipment grounding
In the electrical grounding body, generally use the steel pipe, angle steel, flat steel, round steel and other steel specially made grounding. The artificial grounding body and the ground wire form a grounding device, so that various earthing of the electrical equipment is connected with the ground through a grounding device. The artificial earthing body has two kinds of vertical embedment and horizontal embedment. The vertical buried pipe, angle steel, round steel grounding body, and have sufficient mechanical strength; ground level buried body with round steel, flat steel, common type, with several ring and radiation type. It is better to use galvanized steel when laying artificial earth in strongly corrosive soil. The steel used in the earth body shall be in accordance with the requirements of thermal stability and uniform pressure.
Q:The anti-theft lock in the steel compression spring is what?
The use of stainless steel spring wire suspension spring wire is advanced, high strength, long fatigue life, the effect is good damping characteristics, spring steel wire, the number and distribution of inclusions, so the chemical, high surface quality, decarbonization, microstructure and mechanical performance requirements.
Q:What is the cold drawn steel material? Why did it break?
20 steel 45 steel Q235B a little more material, no annealing treatment
