Product Description:

The pattern shape

A tread surface plate is called a pattern plate, English Name: Diamond plate. The pattern of lentil shaped, diamond, round bean

Shape oblate shape, mixed, the market to the most common lentil shaped.

The specific application of

Pattern plate appearance, can slip, enhanced performance, and many other advantages,such as saving steel in transportation, construction, decoration, equipment around the floor,machinery, shipbuilding and other fields has been widely applied. In general, the use of side of the mechanics pattern plate performance, mechanical performance requirements is not high, so the pattern plate quality mainly flowering rate, as the pattern of pattern height, height difference. At present the common thickness on the market ranging from 2.0-8mm, the width of common 12501500mm two.

The relevant standards

In accordance with the provisions of national standards GB/T 3277 pattern plate, patternheight should be greater than or equal to the thickness of the 20% substrate.

Theoretical calculation of weight

Pattern plate, according to the material (aluminum alloy, stainless steel, ordinary steel etc.)different patterns of different shapes and different weight per square meter adjustment.

Class B common carbon steel rolling, the provisions of chemical composition meet the GB700"ordinary carbon structural steel technical conditions".

Pattern plate of high no less than 0.2 times the thickness of the substrate;

Checkered steel plate according to the weight of the actual weight of delivery or theory;

Mark example: made of Q235-A, size 4*1000*4000mm.

Peaberry pattern plate, mark it as: round bean plate Q235-A-4*1000*4000-GB/T 3277-91

Diamond pattern plate, mark it as: diamond pattern plate B 3-4*1000*4000-GB 3277-82

Steel with hot-rolled state of delivery;

Checkered steel plate surface without bubble, scar, crack, folding and inclusion, plate without delamination.

The surface quality is divided into two levels:

The general accuracy: steel surface with a thin layer of oxide scale and rust allowed, due to other local defects on the surface of oxide scale formed off rough and height or depthexceeds the allowable deviation of the ancient.

Burr height is not obvious and not more than the individual trace lines high allows patterns.The largest area of a single defect pattern with the square of the length of not more than.

High precision: steel surface with a thin layer of oxide scale, allowing the rust and the height or depth of no more than other local defects of half the thickness tolerance.

Pattern intact, a height of not more than half of the tolerance of thickness of the local slightburr allowed patterns.

Q:What can be painted on galvanized steel sheet?
The surface of galvanized steel or galvanized iron sheet (also called galvanized iron sheet) is often stained with grease or antirust oil. It must be removed by solvent or detergent, and then the surface treatment method is adopted. Usually use a primer thinner to clean the surface.
Q:Stainless steel plate and steel welding
With almost 2.5 of the welding, and certainly not the same as before the color. You can buy acid lotion passivation, and then washed with water, basically with stainless steel, the original color is not much
Q:What are the properties of deep drawing properties in sheet steel?
Refers to the change of the thickness of steel plate and the change of plane (length and width direction) when the steel plate is pressed.
Q:How can steel plates with a thickness of 1MM be welded?
The seam is also called the wheel welding equipment for the production, mainly uses fuel exhaust pipe seal. The principle is similar to that of spot welding. The difference is that the output current is uninterrupted.
Q:Can 16Mn steel plate be used instead of Q345D steel plate?
If the use of Q345D instead of using 16Mn, that can be, but 16Mn instead of Q345D can not, and also can not buy 16Mn steel now, that is the old number, and the latest brand is Q345A
Q:Larson steel sheet pile and what is the difference between the hot cold
Therefore, the same technical parameters, usually hot-rolled, will be slightly lighter proportion.For example, 14mm cold bend and 15.5mm SP-IV steel sheet pile, if they are 400mm width, cold-formed steel sheet pile will be heavier than hot rolled steel pileCold-formed steel sheet pile has 8-10mm thickness, although the product is light weight, but the technical parameters are correspondingly reduced.
Q:Why is the water stop steel plate placed in the middle of the wall?
Of course not. It's in the middle of the perfectly accurate, roughly the middle of the wall. General concrete wall, if there is double layer steel bar, placed in the middle of the two layer of steel bar, when placed with short steel welded fixed on the steel skeleton, pay attention to water stop steel plate, not with the structure steel affixed together.
Q:How can the offset film affixed to the cold-rolled steel sheet be removed?
Hand cream can also be achieved to remove the effect of self-adhesive, hand cream contains a lot of water (generally more than 70%), water contains a certain amount of surfactant. Surfactant has good wetting, permeating and dissolving ability. It can quickly penetrate between the adhesive and the surface of the object, so as to achieve the goal of cleaning. You can also find some similar products, such as creams, facial cleanser and detergent.
Q:What is the hardness of the wear-resistant steel plate?
WZB-NM500 is the production of Wugang is more than 450 hardness of HB class can be used welding of high strength wear-resistant steel structure, the manufacturing equipment is suitable for use in high wear, high impact situations, but also can be used as high strength structural steel yield strength more than 700MPa. His hardness can reach about HV1300.
Q:Why should the back of the steel sheet pile cofferdam be pumped after the construction of the pile cap?
Loading and unloading steel sheet piles should be operated by two points lifting method. The number of steel pile piles should not be too many at any time, and attention should be paid to the protection of the locking hole to avoid damage.
