Usage/Applications

-The Square Steel is normally used as structure steel.

-Row material for other structure steel like steel angles, channels, I-beams, H-beams, etc…

-Row material for steel pipes.

 

Packaging & Delivery

-Packing Detail:

1, The products can be packed in bundles by steel wires.

2, The weight of each bundle no exceed normally 3 tons.

-Marks: We make tag marks and color marks for each bundle. The tag marks with white background and red company log will be tied up to each bundle. The information is usually including basic information of company and products like product name, specification, etc...and other information required by customers. As for color marks, we will paint both ends of each bundles to make sure that it will be more convenient for customers to distinguish theme from other products.

-Delivery Detail: 30~45 working days after receive buyer’s T.T. or L/C.

 

Payment:

-Invoicing on theoretical weight or actual weight as customer’s request.

-FOB, CFR or CIF.

Q:Round and square steel which is strong
Of course, the round steel is stronger. There was not because round steel is not convenient, a bar where rolling will affect the construction safety and progress. Log and wood with the same size and length to try to lift the increasing weight of the timber is certainly the first break. The cylinder is the strongest and most durable.
Q:The steel and wood preservative in the flower is how to connect
A dovetail screw / stainless steel fixed special anticorrosive wood keel screws,
Q:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Say so much, directly tell you, if it is with square steel (main keel), that spacing in 1--1.2 meters is absolutely no problem, the standard is not allowed more than 1.2 meters, but the actual construction exceeds the situation or some. If there is no special circumstances (such as from the wall out more than 300mm or), then no problem, rest assured!!!
Q:100*100*2.5 square with 20 square meters of housing security light steel structure:
Sun room safety also includes many other factors, such as the sun room design is reasonable, whether the material is special, the construction team is professional, and so on, to summarize the sun room safety including safety design, material safety, construction safety, maintenance safety. Consulting Zhejiang Baiyu Dinglong sun room can not understand the place, professional and technical guidance.
Q:Building with steel or steel plate?
A channel is more reasonable, the steel is solid, itself is very heavy, do not use solid steel structure, are used in pipe, angle steel, I-beam, etc. are all hollow
Q:25-30mm drill pipe steel, to drill a lot, need what equipment
Drill with magnetic base.Magnetic drill is also called magnetic block drill. The magnet drill is to change the electric field at the bottom of the magnetic drill after energizing. The magnetic field is absorbed on the steel structure, and then the magnetic drill motor runs at high speed to drive the drill bit and realize the drilling of the steel structure.
Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:The difference between the steel chrome and paint
The utility model has the advantages of bright color, strong visual impact, good surface finish, easy cleaning, moisture resistance and good fire prevention performance. And spray paint is sprayed directly, and thenGeneral steel can paint and painting the door company most paint steel, but you must ask whether to do heat treatment, because the paint that is backward spray drying
Q:What is the cold drawn steel material? Why did it break?
This should be the problem of raw materials, raw materials are hot-rolled round steel or steel, raw material impurities, there will be extended by cold drawing fracture phenomenon. Materials for large steel mills are proposed.
Q:As for steel structure steel, how appropriate
The size of the material is strongly related to the load on your floor, and the roof material and column size are also related to your span and the local Blizzard loads. You can choose the size of the material according to the local conditions.
