Custom Open Web Steel Truss Joist En1090 for Industrial Roof Floor

Product Description

Our Custom Open Web Steel Truss Joist is a high-performance prefabricated structural component certified to EN1090 standards, specially developed for long-span industrial roof and floor systems of steel structure buildings. The rigid open-web truss frame efficiently transfers building loads, breaks the limitation of traditional solid steel beams, and reserves enough space for mechanical, electrical and plumbing layout. All trusses are precisely customized according to project span and load requirements, widely used in commercial and industrial large-space constructions.

Product Structure Composition

Each complete steel truss joist consists of four core parts: top chord, bottom chord, diagonal web members and bearing ends. The top chord bears the pressure from floor or roof panels; the bottom chord undertakes tensile force; crossed web bars form hollow open gaps for pipeline passing; bearing ends act as connection supports to fix trusses on main steel beams. The integrated welded structure guarantees overall rigidity and long-term structural stability under heavy loads.

Core Advantages

1.Open-web hollow design realizes efficient MEP integration, pipes, wires and air ducts can run through trusses directly, saving building height and cutting construction cost.
2.Lightweight but high bearing capacity, reduce total steel consumption of the whole steel structure building.
3.Full factory prefabrication, tight dimensional tolerance, greatly shorten on-site construction period and reduce labor cost.
4.Modular sleek lines can be exposed as architectural decorative elements for modern industrial buildings.
5.Support full customization of size, load and surface treatment to match all unique project design demands.

Global Application Scenarios

Production & Quality Control

This EN1090 certified open web steel truss joist has been supplied to global engineering projects for years, perfectly fit for long-span floors and roofs of industrial warehouses, logistics distribution centers, large manufacturing workshops, sports halls and exhibition venues. It eliminates intermediate support columns to create wide unobstructed interior space, which cannot be realized by ordinary solid steel floor joists.

All trusses are manufactured under international authoritative standards including EN1090, ISO9001 and AWS D1.1. Strict raw material inspection, automatic welding, dimensional recheck and anti-rust treatment are carried out in our factory workshop. Every finished steel truss passes structural load simulation test before delivery to ensure durability and consistent safety performance in harsh working conditions. We provide 1-year structural warranty for all finished products.
