Together with the channel and angle, manufacturers classify strip bulb as black shaped steel. It is distinguished by a special bulbous profile, made with a flat wall or with a specific rounded head and shelf.
Strip Bulb is produced in accordance with existing standards. According to the shape of the profile, it can be symmetrical, with two shelves, and asymmetrical, with only one shelf.
Symmetric and asymmetrical bulb strip is produced using hot-rolled technology. At the same time, in a product with two shelves, the distribution of metal over the cross section occurs more rationally and economically, which contributes to a greater demand for a symmetrical profile.
The profile is able to withstand very significant loads. Therefore, it is used in structures that have special requirements for strength. You can buy strip bulbs for making stiffeners, hull beams and other reinforcing elements of cargo and passenger ships.
The rounded shape of the steel reinforcing elements provides the ship’s hull with maximum bending resistance.
