An unique production of steel welded I-beams with automatic control of the welded seam position ( two automated welding lines made in Finland and Italy).
The advantages of the electric I-beam:
— reduction of structures weight compared with the rolling beam by choosing the optimal composite section, including asymmetric one;
— the possibility of different steel types application in a beam cross-section for shelves and walls;
— higher strength and stiffness compared with the beam of square cross-section;
— wastes minimizing by making the beam of required length.
"Protos" Ltd produces electric I-beams of the following types:
— the I-beam of constant cross section (height 200-3500 mm, shelf width 100-1500 mm, length 3-24 meters);
— the I-beam of variable cross section;
— the I-beam with variable radius of curvature (radius) - an exclusive type of beams, analogues of which have not yet produced on the territory of Belarus;
— the beam of box cross section;
— the beam of cross-shaped cross section.
We produce all kinds of products according to customers’ drawings.
It is possible to manufacture the products from given material..
Quality control is carried out by OTC and its own Laboratory of Nondestructive Testing using the method of thickness measurement, visual-optical and ultrasonic methods of control for welded joints. The laboratory has the certificate of the National Accreditation System of the Republic of Belarus No. BY / 112 2.4700 dated 16.10.2015.
The quality of welded I-beam can be proved with documents according to GOST 23118-99 and Specifications BY 700010872.002-2011..
