Seamless squaring the circle - VTS®-edgeTubes are seamless square and rectangular hollow sections that are primarily used in agriculture, constructions, mechanical engineering and mobility.
Discover the world of seamless hot-rolled hollow sections from voestalpine Tubulars and experience quality, reliability and innovation at first hand. voestalpine Tubulars has many years of experience in the production of seamless round tubes and stands for quality, flexibility and safety. We will thus be able to produce hot-rolled seamless square and rectangular hollow sections up to 20 mm wall thickness.
Product characteristics:
Tighter corner radius - Ra ≤ 1,6 x T ( Ra up to ≤ 1 x T depending on dimension & wall thickness upon request)
Defined design of outside corner - Due to hot-rolling process
Larger cross-sectional area - Due to tighter corner radius which enables wide range of applications
Excellent weldability - Less welding filler required for further processing
No weld seam - Due to seamless pipe production, No mechanical weak point
Superior load-bearing capacity - Larger spans possible
Low residual stress - Due to homogeneous structure
Weight minimisation - Due to the availability of higher and high-strength steel grades, while maintaining load-bearing capacity
