Product Introduction of Steel Profiles
Steel Profiles, sometimes called sections, include angles, channels, I-beams, squares, H-beams, etc.
Steel Profiles are objects with a certain geometry made of iron or steel and materials with a certain strength and toughness (e.g. plastic, aluminium, glass fibre, etc.) through processes such as rolling, extrusion and casting.

Application And Classification Of Steel Profiles
According to the different smelting quality of the steel, the section steel is divided into ordinary section steel and high quality section steel. Ordinary section steel is divided into large section steel, medium section steel and small section steel according to the current metal catalogue. Ordinary sections can be divided into I-beams, channels, angles, rounds, etc. according to their cross-sectional shape. Large sections: large sections of I-beam, channel, angle and flat steel are hot-rolled, while round, square and hexagonal steel are forged and cold-drawn in addition to hot-rolled.
I-beams, channels and angles are widely used in industrial buildings and metal structures, such as plants, bridges, ships, agricultural machinery and vehicle manufacturing, power transmission towers, transport machinery and often used in conjunction. Flat steel is mainly used as bridges, house frames, fences, power transmission, ships, vehicles, etc. Round steel, square steel used as a variety of machinery parts, agricultural machinery accessories, tools, etc.
Medium section steel: Medium section steel in work, channel, angle, round, flat steel use and large section steel similar
Small section steel: small section steel in the angle, round, square, flat steel processing and use and large similar, small diameter round commonly used as construction steel.
Quality / Duration of Steel Profiles
Steel products are particularly susceptible to deterioration due to corrosion or may often require elaborate treatment before being used or further processed.
One particularly frequent cause of damage is rust due to seawater, rain, condensation water in the means of transport, cargo sweat or condensation inside the packaging. Unsuitable means of transport, ships with poor hatch covers or without ventilation facilities, damaged containers, uncovered railroad freight cars and trucks, incorrect storage in the open, use of unsuitable tarpaulins, exposed loading in wet weather conditions, and variations in temperature and climatic conditions during long voyages may result in rust damage.
If a solid bond (adhesion) between concrete and reinforcement steel is to be achieved, relatively clean steel from which loose rust has been removed should be used, i.e. slight surface rust may even be advantageous. Care must, however, be taken to ensure that the diameter of the concrete reinforcement steel still fulfills the requirements of the statics calculations once it has been pickled or sandblasted. Prestressed concrete reinforcement steel, in contrast, must be rejected if it exhibits even the slightest corrosion.
The oxidation layer (scale) which is formed on the surface of steel during hot-rolling or annealing provides limited corrosion protection. This layer does, however, complicate application of anti-rust coatings or galvanization.
Some special, large and angle profiles have a hot-dip galvanized or zinc sprayed finish and are thus protected from corrosion.
Packaging of Steel Profiles
Steel profiles of all kinds are transported in bundles held together by steel strapping, for the most part without any further packaging.
Special steels should be protected from corrosion and mechanical stresses (e.g. scratching and buckling) and are generally packaged using corrosion protection (e.g. oiled paper or appropriately lined boxes or wood/corrugated board structures.
