Portal steel frame steel building is the simplest and most practical building structure sysytem,which is formed by the main steel framework linking up H section,Z section and U section steel components,roof and walls using a variety of panels and other components such as windows, doors,cranes,etc.
It can be widely used for warehouse, workshop, garage,garden storage shed, airpaort,office building,apartment,and all kinds of steel buildings, metal buildings, modular house, steel frame for other riveting and welding parts. etc.
The sizes can be customized according to requirement.
1.They are super-quick to build at site,as a lot of work can be pre-fabbed at the factory.
2.They are flexible,which makes them very good at resisting dynamic forces such as wind and earthquake forces.
3.A wide range of ready-made structural sections are available.
4.They can be made to take any kind of sharp,and clad with any type of material
5.A wide range of joining methods is available,such as bolting,welding and riveting.
Portal steel frame building can be single span or multi-span,it is determined by the requirement of later use.
