SPAR experience gave birth to Tube Solutions, a special division specialized in high-tech laser welded tube production. SPAR range has now a brand new product to offer: a high quality tube that can be used for any application requiring the greatest performance, not only from the technical point of view but also as far as the excellence of the provided service is concerned. Tube Solutions uses for its production and quality control processes only updated instruments, such as laser welding lines and 2D laser cutting machines.
SPAR Steel’s reputation and goodwill stands on our expertise and industry experience. SPAR believes in evolving ourselves on the basis of constant progress and inclusion of new technologies that are deployed to satisfy the most demanding expectations, for a wide range of uses.
Thanks to our great know-how on Hot Rolled coils and GI coils, and our incomparable ready stock, we can choose the raw material having the most appropriate mechanical and surface characteristics to avoid waste, rework and any thermic treatment of our steel tubes.
During our tube forming process, the dimensional accuracy is obtained by our step by step processes, so as to produce a precision tube offering tolerances in sizes much stricter than the normal standards in use. We are very particular about coils we choose for manufacturing our fine engineering products and those which can withstand the test of time. In line with this, all production lines use raw material with standards based features that allows us to offer the highest degree of mechanical characteristics of our tubes. This makes any last moment thermic treatment on the tube redundant.
Conventional welding of structural members is prone to inconsistency in terms of acquired strengths by the resulting joints across the length. The tiny air cavities and voids formed during the welding acts as region of stress-concentration and can become reason of crack propagation and failure of joints.
SPAR’s experience has taught us that the type of welding source will cast an influence on the welding seam morphology and mechanical features of the joints.
SPAR’s specialized Tube Solutions laser welding presents far greater advantages. The laser source produces a predictable and extremely narrow welding seam and allows for a complete penetration into all our thickness of the slit member being welded. Due to homogeneity achieved after laser welding, SPAR tubes have the ability to perform reliably throughout its service life.
Our latest machinery and Tube and Pipe manufacturing know-how helps us reach a level of very small thermic distortions and far better dimensional tolerances on the inner and outer diameters of our tubes.
This process assures the welding zone to become extremely resistant and capable of enduring tensile loads, bending moments and shear force during its application in demanding scaffold industry.
