Product Description

Portal Frame Station Steel Construction is a rail transit station building solution that adopts a solid-web portal rigid frame system as its main load-bearing skeleton.

Formed by rigid connections between steel columns and roof steel beams to create portal-shaped frames, this product enables large-span column-free spaces, delivering architectural advantages of wide bays, high clear heights and rapid construction for station buildings.

Meanwhile, our products feature core strengths including excellent structural performance, high economic efficiency and environmental friendliness, which well meet the requirements and interests of small- and medium-sized station buildings.

Compared with traditional concrete structures, the Portal Frame Station Steel Construction made by our factory boasts remarkable advantages in multiple aspects for rail transit buildings.

The portal rigid frame structural system has multiple classifications, among which the solid-web portal rigid frame is the most suitable type for our Portal Frame Station Steel Construction product. Meanwhile, we can also customize products of other structural types for you.

Structural Type	Structural Features	Application Scenarios
Solid-web Portal Rigid Frame	Welded H-steel / hot-rolled H-steel, rigid beam-column connections	Standard stations, canopies, vehicle depots
Corrugated-web Portal Rigid Frame	H-steel with corrugated webs replacing flat webs	Large-span projects, material-saving requirements
Lattice Portal Rigid Frame	Truss-type beams and columns with high force-bearing efficiency	Super-large-span and heavy-load scenarios
Multi-span Portal Rigid Frame	Continuous layout of 2-3 spans, no cranes	Multi-track vehicle depots

In addition, our Portal Frame Station Steel Construction product features a wide range of main application scenarios, mainly covering:

▷ Elevated Station Building

▷ Column-free Platform Canopy

▷ Train Stabling & Inspection Depot of Rolling Stock Yard

▷ Maintenance Depot of Rolling Stock Yard

▷ Metro Parking Yard

Our Portal Frame Station Steel Construction product mainly consists of three major parts: main rigid frames, secondary structures and enclosure systems. Its key components include:

Main Rigid Frame
Steel Column	Vertical load-bearing & lateral force resistance
Roof Steel Beam	Bear roof loads, rigidly connected with columns
Haunch	Reinforce joints and improve flexural bearing capacity
Secondary Structure
Purlin	Support roof panels and restrain beam flanges
Wall Beam	Support wall panels
Inter-column Bracing	Ensure longitudinal stiffness and transfer horizontal forces
Enclosure System
Roof Panel	Waterproofing, thermal insulation and decoration
Wall Panel	Enclosure and thermal insulation

Project Experience

Rushannan Railway Station is located in Rushan City, Shandong Province, China, a typical station project undertaken by EHSS. The total construction area of the project is 10,000 square meters with a steel consumption of 1,358 tons. The platform canopies adopt portal frame structure, representing one of the typical applications of our Portal Frame Station Steel Construction products.

FAQ

Q1: What is the construction period for steel structure products?

Our Portal Frame Steel Construction adopts a factory prefabrication plus on-site assembly model, which can greatly shorten the construction period to 2–3 months.

Q2: How do you handle corrosion and fire protection for your products?

Our products use painting (zinc-rich epoxy primer + epoxy micaceous iron intermediate coat + polyurethane topcoat) or hot-dip galvanizing for anti-corrosion treatment, and fire-retardant coatings or fireproof board cladding for fire protection treatment.

Q3: How to choose between portal frames and steel grid structures?

In practical projects, a combination of portal frames and grid structures is commonly adopted; other options are determined based on different requirements and application scenarios.

Scenario	Recommendation	Advantages
Platform Canopies, Depot Warehouses	Portal Frame	Cost-effective, fast construction
Long-span Roofs of Station Building Halls	Steel Grid Structure	Versatile shapes, capable of larger spans

Q4: What is the approximate steel consumption of Portal Frame Station Steel Construction?

The steel consumption of the product is mainly affected by span, column spacing and loads, which shall be determined according to specific requirements. Reference data are as follows:

Scenario	Steel Consumption
Platform Canopies, Small Vehicle Depots	25-35 kg/m²
Maintenance Workshops, Large Vehicle Depots	35-50 kg/m²

Q5: Can renovation be carried out?

Portal frame structures feature high flexibility for renovation, allowing the addition of mezzanines, suspended equipment loads, extended spans and increased lengths.
