Product Description:

Spring Steel can be divided into two types. One is carbon spring steel, and other one is alloy spring steel.

Alloy spring steel is based on carbon spring steel, by adding one or more alloying elements to improve the mechanical properties, hardenability and other properties to meet the requirement for manufacturing all kinds of spring steel.

Q:Are galvanized flat steel and angle steel the same price?
No, generally speaking, galvanized flat steel is more expensive than angle iron
Q:Do lightning protection, lead out of the galvanized round steel, flat steel needs to be inspected?
When you buy hot galvanized round steel and flat steel, please provide inspection documents. In addition, in the procurement of materials must be explained that hot galvanizing, or else the business to provide you with cold plating will not work; there is a certain price gap between the two.
Q:Galvanized flat steel how much is one meter?
Formula of flat steel: width * thickness * 0.00785 (kg/m), zinc coating weight: 1.06Galvanized pipe formula: (outer diameter wall thickness) * wall thickness * 0.02466 * 1.06, DN25 galvanized pipe outer diameter 33.5, GB thickness 3.25, weight: 2.57kg/m, DN32, outer diameter 42.3, wall thickness 3.25, weight: 3.32kg/m. DN stands for nominal caliber.Angle formula (approximate): edge width * thickness * 0.015, 4# angle iron weight 2.422kg/m
Q:Where is the use of flat steel in electrical use?
The flat steel used in the project consists of two types: galvanized and non galvanized. Galvanized is mainly used in decorative materials and pipes, such as rings, hoop and so on;
Q:What is the negative deviation allowed by the national standard for galvanized flat steel of 40*4?
40*4 galvanized flat steel GB permitted negative deviation value is the thickness deviation value is 0.2mm, the deviation 0.4mm, the width deviation value is the upper deviation 0.5mm, lower deviation 1.0mm
Q:What is flat steel, please?
Steel strip steel rectangular and with pure edge of cold drawn steel, stainless steel flat steel. Stainless steel flat can be semi-finished steel. There are cold drawn polished stainless steel flat and hot-rolled acid white and sand blasting stainless steel flat. The raw material for producing stainless steel flat bar is stainless steel square billet, and the finished stainless steel flat bar is produced by hot rolling, normalizing or hot rolling, pickling (or sand blasting), cold drawing and polishing. The two sides are equal in width. The specifications are expressed in millimeters of edge width * * edge thickness. Such as 30 * 3, that is, width of 30 mm edge, 3 mm thick edge of stainless steel flat side.
Q:Can lightning protection earthing steel bar be directly welded with thread steel?
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
Q:Building poles, outdoor flat steel, the deeper the buried depth, the better?
Building poles, outdoor flat steel, buried depth is not as deep as possible. According to the standard requirements, the level of the embedded depth is not less than 0.6 meters.
Q:What is the appearance of hot galvanizing and cold galvanized flat steel?
There is no heat, heat processing process is differentDifferent galvanizing methods, such as hot dip plating or electroplating, etc.Finally, performance is different
Q:Friction coefficient of steel pipe and flat steel on roller table!
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
