HIGH STRENGTH STEELS
Small amounts of alloying elements, such as niobium, vanadium or titanium, are added to the chemical composition of high yield strength steels to enhance their physical and mechanical properties, ensuring in particular greater mechanical strength and corrosion resistance. This chemical structure also makes it possible to reduce the carbon content and thereby improve some criteria, such as weldability and ductility.
These steels are particularly indicated for situations where the strength-to-weight ratio is a determining factor, namely in the development and construction of load-bearing structures, cranes, aerial platforms, telescopic functions or heavy-duty vehicle trailers (increased payload).
This solution also allows for a significant reduction in the thickness of the materials, without losing their essential properties.
The material is available in geometric ties, strapped with steel bands, in hexagonal, square, and/or rectangular shapes. To facilitate handling (loading/unloading), all the ties are supplied with polyester straps suitable for the weight of the tie.
Each tie is supplied with a label attached by a metal clip, ensuring the identification of the product and consequently its traceability.
During manufacture, all tubes are coated with a protective oil, which has a high hydrophobing power, to protect the surface against corrosion. Unless otherwise stated by the customer at the time of the order/inquiry.
On shipment, all orders are accompanied by the respective inspection certificate according to EN 10204, in accordance with the product’s applicable standard.
Hot-dip galvanized tubes can be supplied, according to EN 10240 A.1/A.2 or ISO 1461, providing greater protection against corrosion.
Special tolerances must be requested when inquiring/ordering.
Possibility of removing the internal welding bead. Possibility of defining the position of the weld bead, according to target value and/or face of the tube.
Possibility of supplying tubes with chemical properties that guarantee their suitability for hot-dip galvanization.
Possibility to specify the CEV value at the time of inquiry/order.
It is possible to supply tubes that meet the requirements compatible with weldability at the corners according to EC3.
Capacity to supply tubes with specific lengths, requested at the time of inquiry/order.
Tubes can be supplied, according to the most demanding deformation capabilities.
The ties can be configured, according to the client's indications, at the time of the inquiry/order. Possibility of using packaging with anticorrosion protection (VCI).
Possibility of requesting specific laboratory tests, not foreseen in the applicable standard (anisotropy, salt fog, metallography, thickness elongation, among others)
