Product Advantages
- Simple construction: The portal frame structure adopts prefabricated components and standardized design, simplifying the construction process, greatly shortening the construction period, and saving time and labor costs compared with the traditional concrete structure.
- Lightweight material: The portal frame structure’s main material is steel, which has lightweight features and high strength to reduce the overall weight of the building.
- Diversified design: The portal’s rigid structure with flexible design adjustment can meet different spatial and functional requirements. The quantity of materials between columns and beams can be increased or decreased according to the design and construction. At the same time, the roof and walls can be freely transformed and expanded according to the actual situation.
- Excellent safety: Steel is tough and has anti-seismic performance, which makes the portal frame structure highly safe and stable in normal use.

Packaging & Delivery
At our facility, all components of the rigid frame structural system are carefully packaged to ensure maximum protection during handling, loading, shipping, and unloading. Our standardized and secure packaging process guarantees that each part of the rigid frame structure system arrives at the destination site in excellent condition and ready for assembly.
-
Steel Structure Components:
All primary and secondary structural steel elements—such as beams, columns, and braces used in the rigid frame structural system—are wrapped with protective materials to prevent surface damage, corrosion, and deformation. Each piece is bundled and secured to minimize movement during transit.
-
Sandwich Panels:
Roof and wall sandwich panels are tightly wrapped in high-quality plastic film to guard against moisture, dust, and abrasion throughout the delivery process.
-
Doors and Windows:
Fragile items like doors and windows are packaged with thick bubble plastic for cushioning and impact resistance during transportation.
-
Bolts and Accessories:
All connection bolts, fasteners, brackets, and minor accessories are placed inside sturdy wooden boxes, which are sealed to avoid any loss or damage.
To accommodate various component sizes and configurations of the rigid frame structural system, we typically use:
-
40’HQ (High Cube) and 40’OT (Open Top) containers for standard or large steel frames.
-
40GP and 20GP containers for smaller, consolidated loads or based on specific client requirements.
-
Oversized items, such as long-span beams or custom-fabricated frames, may be shipped via open transport or flat-rack containers for safe handling.
Available Ports for Shipment:
We export through major Chinese seaports including:
-
LIANYUNGANG PORT
-
SHANGHAI PORT
-
NINGBO PORT
-
GUANGZHOU PORT
Our logistics team ensures that every delivery of the rigid frame structure system follows international shipping standards, with attention to cost-efficiency, protection, and on-time arrival.
