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:The difference between color steel and stainless steel
The difference is that an ordinary steel plate is painted with antirust paint and one is made of stainless steelThe same is true of steel, steel and steelIt's essentially different
Q:What are the reasons for the steel mesh on both sides of the back pouring belt?
In order to prevent the concrete from changing the temperature, the post pouring construction belt is called the temperature post casting belt.
Q:Stainless steel plate how to cast mirror plate?
Jacksonlea brand stainless steel polishing pasteThe supply of Jacksonlea brand stainless steel polishing paste, with the use of polishing wheel, can provide excellent gloss, providing the whole face of Gaoping. According to the customer's quality requirements, can provide rough, medium, fine specifications, with cloth, hemp wheel use.
Q:Q195 galvanized steel plate, is it hot or cold?
The difference between cold rolling and hot rolling is not in the smelting process, but in the temperature at which the steel is rolled, or the temperature at which the steel is rolled. When the final rolling temperature is lower than the recrystallization temperature of steel, it becomes cold rolled steel. Hot rolled steel is easy to roll and has high rolling efficiency, but the steel is oxidized under hot rolling and the surface of the product is black and gray.
Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
HPB's full name is hot rolled round steel (HPB is Hot-rolled Plain Steel Bar) in English, commonly known as wire rod, diameter 6 - 12 rounds of the most common, including HPB235 and HPB300. You haven't met HPB400?. HRB400 and RRB400 are treated steel bars in order to have such high strength. But the general strength, ductility will be reduced, as the saying goes, "tossing" is not resistant to toss about.
Q:What is the thickness of the paint board?
As a decorative wall painting board, the scale is greater, a 122*244*1.8cm UV paint board. The most common market in general is 15-18mm, one of 18mm's highest market share, in addition to 12mm, 9mm, 5mm thickness, if it is made, manufacturers generally have the ability to make 3mm-35mm between any thickness out.
Q:What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water stopping principle: the water stop bar is expanded by water absorption and then squeezed with concrete to stop the void.Construction technology: the stop bar is square long strip, and parallel lap method is adopted when connecting. No break point can be left in the middle. Construction units in order to facilitate, often like to use the water bar, concrete pouring in the completion of the pressure on the wall concrete pouring surface, or reserved groove, two times mosaic.Good and bad analysis: simple construction, less investment, relatively economic. But there is no water stopping effect and the water stopping steel plate is good. There are many unforeseen problems during the construction process. One is that the reinforcing bars are not close enough to be laid. Two is the time is too long, moisture absorption expansion, the impact of the effect, especially in the rainy season, air humidity, rainfall, water retention is worse. Three construction joints are not smooth, poor contact. Usually, this method is not ideal for stopping water. For example, when the water stop bar is installed, the retaining of the groove is too large to be fixed effectively; the small inlay is not in place; when the concrete is poured, the utility model is easy to shift under the action of the concrete buoyancy.
Q:Why is the water stop steel plate placed in the middle of the wall?
A water stop steel plate is an ordinary thin steel plate, not a waterproof coiled material, not a rubberized fabric, but imagine if a steel plate is placed on the outside of the concrete wall
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
No minimum, no maximum, no requirements, what kind of plate can be welded, but the welding method is not the same as welding equipment.
Q:What does "Z" mean to the performance of steel?
The Z plate is used to prevent lamellar tearing of plates, the main connections at the plate, if the plates in the thickness direction bear significant tensile stress on the sheet.
