(zinc) Coatings on Ferrous Hollow and Open Sections, class ZE50/50. The minimum average zinc coating weight is 50 grams per square metre on the inside and outside surface of the tube. Orrcon Steel applies a clear water-based polymer coating called Clear-Tec to the external surface of ALLGAL® which provides additional shelf life protection.

Currently three methods are being used in North America for the manufacture of HSS.
B. Steel framing is the M.S.U. standard for all interior doorways, paired with flush wood doors. (See Division 8 section 081416 FLUSH WOOD DOORS), and for interior windows. C. When used on exterior openings, steel doors and frames shall be galvanized. D. All public and personnel doors shall be a minimum of 36 wide to provide barrier free access STRUCTURAL STEEL SECTION FACTOR General Guidelinessection. One exception is circular hollow sections. See page 5. Where a steel section abuts or is built into a fire resisting wall or floor, the surface in contact with or the surface within the wall or floor is ignored when calculating Hp. However, the value A is always the total cross sectional area of the whole steel section.

Structural Galvanized Hollow Section Product Description Pre-Galvanized Steel Pipe is widely applicated in buliding constructions, pipe of industrial, water pipe, fence equipment, telecommunication tube as well as greenhouse tubes for different planting and bredding business. Structural Hollow Section - CondesaFire resistance. Protecting steel tubular sections by means of surface coating is easier and more economical than open sections due to the absence of cavities and the lower surface area to be covered. Passive protection:Structures made from Tubular Sections offer higher fi re resistance than open Structural Tubular Steeld. The mass of a length of hollow section shall not be less than 96% of the specified mass of the nominal section. e. Hollow sections produced by electric resistance welding shall have the external weld upset removed. Circular sections 168.3 OD are internally scarfed to remove internal weld upset. It is not mandatory to remove the
Circular hollow sections - These are manufactured up to a maximum size of 300 mm NB The thickness of these steel hollow sections vary from 2 mm to 10 mm, depending on what application the tubes would service. Each steel hollow section features a high strength to weight ratio that results in Hollow Sections Dimensions, Square Hollow Sections Hollow Sections Dimensions, Structural Hollow Section Dimension, Square Hollow Sections Dimensions, Square Hollow Section Sizes, Rectangular Hollow Section Dimension, Rectangular Hollow Section Sizes, Hollow Section Weight Calculator Surface:I xx cm 4:I yy cm 4:r xx cm:r yy cm:Z xx cm 3:Z yy cm 3:J cm 4:B cm 3:Area per mm 2:25x25
