Welcome to ECBAY
ISO9001:2000 steel city bridge
ISO9001:2000 steel city bridge

steel city bridge *high strength and durable *easy and fast erection *save energy/environmental *low cost


1.high strength and big stiffness , relative to the concrete bridge can be reduced trabecular high

and self-respect

2.Due to the steel isotropic, quality of a material is uniform and modulus of elasticity, that make

 steel  bridge in the working condition and calculation compared with the assumption

3. Steel bridge generally USES factory, site splicing, the construction period is short,

processing convenient and not affected by seasonal effect

products main material and components
main frame    column and beam---Q235/Q345 steel with  high strength and stiffness,high weight bearing
secondary steel frame  C steel,Z steel , square tube , steel angle and bracing

door and window

PVC window,aluminum alloy window,sandwich door and sliding door
roof and wall material  corrugated sheet, color plate,sandwich panel


Semi-transparent skylight belts, Ventilators, down pipe etc


anchor,ordinay,high strength bolt
single-layered medium-sized factories and warehouses  urban elevated road

high-and ultra-high-rise buildings   

large-span public buildings

office buildings and residential building

large long-span bridges and tower mast structure  

industrial platforms and racks

single-layered heavy plants
widely used   *modern industrial construction, civil construction, public buildings, municipal works, road and bridge projects
quality advantage *high strength, light weight, good material, high reliability and short-duration high level of industrialization
Engineering design capability 1,Based on the concept of modern design and corresponding national standards
 2,most optimized design high-efficiently with the use of advanced internal aid design software, such as PKPM and 3D3S
 3,complete set of production and installation drawings of steel structure to ensure the high-efficient and accurate operation

  Next is our Production technology process


Our makets are North America, South America, Eastern Europe,

Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western


These are our Yili parts of projects in many countries and we get

good feedbacks


                                            YILI COMPANY


QingdaoYili Steel Structure&EngineeringCo.,Ltd  adopts the light steel structure  and we follow the relevant 

domestic norms and regulations. And we design them by using advanced computer-aided design software .

We manufacture and process them by using the advanced domestic equipment with great care. Thus we

 ensure the optimization and perfection of the building systems and construction quality fundamentally.

if you are not familiar with the detail of products,please reffer to this

photo and give us your questions and reqirements

we need you supply the answers of questions as following
