cold and hot finished structural hollow sections size Rolling

The tested hot-formed and hot-finished hollow sections were of dimensions 180 mm 180 mm 12.5 mm, while the cold-formed hollow section was of dimensions 200 mm 200 mm 12.5 mm. Surface discontinuities including rolled-in scale and pitting, indentations and roll marks, scratches and grooves, spills and silvers, blisters, sand patches, cracks, shell, and seams were examined. Cold And Hot Finished Structural Hollow Sections Size Rolling - Image ResultsStructural shapes like I-beams are usually hot rolled. The formula of steel used for I beams is different than used in cold forming. Its less ductile and harder, which makes it tougher to bend cold, hence the use for structural shapes that carry a lot of weight! Cold roll forming has many commercial and industrial uses.

Advanced high-strength structural hollow sections Strenx Tube 960MH is an HF-welded cold-formed structural hollow section made of hot-rolled high-strength steel with a minimum yield strength of 960 MPa. Its high strength combined with naturally stiff form of welded hollow section enables construction of stronger and lighter structures.

Cold formed rectangular hollow section (RHS) is formed from hot rolled coil and has a smooth blue/grey coloured finish and a raised internal weld seam that can vary greatly depending on the mill of manufacture. Coils vary in size up to around 25 tonnes and 2 metres wide. Comparative experimental study of hot-rolled and cold-formed cold and hot finished structural hollow sections size RollingA total of ten structural hollow sections were examinedfive hot-rolled and five cold-formed of the following nominal section sizes-1001004, 60604, 60404, 40404 and 40403. The nominal yield strength of the hot-rolled tubes was 355 N/mm 2 while that of the cold-formed tubes was 235 N/mm 2. Design software and tools - SteelConstruction.infoTables are provided for both S275 and S355 grades for open sections, S355 and S420 grades for hot-finished hollow sections, and S355 grade for cold-formed hollow sections. Comprehensive design data is also provided for bolts and welds, rolling tolerances are given, and there are comprehensive sets of explanatory notes for both the Eurocodes and cold and hot finished structural hollow sections size Rolling

Rolling hard roll weight is generally 6 to 13.5 tons, the coil diameter of 610mm. The general cold strip mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the mechanical properties of the corresponding standard specifies.
