High-grade steel - Import export

PT screws for thermoplastics: Thread rolling screws for direct screwing into plastics, Thread 30° or 60° KTG screws for thermoplastics: Single-start or double-start thread (high, low) Thread rolling screws are extruded for larger batch sizes and turned for small batch sizes (Turned parts for direct screwing) High tensile and highly stressable connection of thermoplastics with considerably longer life endurance Thread rolling without chips and loss of material Minimum radial tension, large thread coverage Process-reliable due to torsion strength Shorter and slimmer screws are possible. Materials: Steel, case-hardened Quenched and tempered steel 1.5523 tempered to 1000 +200 N/mm², high-grade steel 1.4567, other materials on request Length: 3 – 160 mm (at lengths from 60 mm only partial thread lengths 4 x d are possible) Thread diameter: 1.6 – 10 mm Special dimensions on request Batch sizes: Standard ex-stores Special screws from 30,000 pieces

The difference that Cor-ten Steel makes becomes obvious when the steel is exposed to extremely high temperatures ( 300-600 c) , which unlike carbon steel it can withstand well.

Steel structure is a metal structure which is made of structural steel components connect with each other to carry loads and provide full rigidity. Because of the high strength grade of steel, this structure is reliable and requires less raw materials than other types of structure like concrete structure and timber structure. In modern construction, steel structures is used for almost every type of structure including heavy industrial building, high-rise building, equipment support system, infrastructure, bridge, tower, airport terminal, heavy industrial plant, pipe rack, etc. We provide turnkey solutions for your steel structure projects.

Our experience in filling cylinders has enabled us to develop our own pump technology which has proved its worth in a number of fields in addition to filling cylinders.
