High and low span steel warehouse construction in Canada

Canglong Group provided a high-low span steel warehouse solution for its Canadian client. The project utilizes a combined high-low span structure, connecting a double-sloped main building with a single-sloped structure of approximately half the height of the main building on one side, creating a unified whole. This approach meets diverse spatial needs while making more efficient use of building area and structural system.

High-Low Span Combination, Meeting Diverse Spatial Needs

The main building features a double-sloped roof structure, connected on one side by a single-sloped structure approximately half the height of the main building. The two parts are structurally connected to form a complete building.

This high-low span design allows for spatial division based on the actual functions of different areas. For example, the higher main space can be used for primary storage, while the lower side can be used for auxiliary storage, equipment areas, or other functional spaces.

Compared to simply constructing a building with a uniform height, the high-low span structure allows for more flexible building space while avoiding the need to design the entire building to be the same height to meet localized needs.

Different Cross-section H-beams to Match Different Structural Requirements

The main structural beams and columns utilize wider cross-section H-beams to provide reliable load-bearing capacity for the main building spaces. The lower, single-slope structure uses narrower cross-section H-beams, rationally configured according to its actual span and load requirements.

This differentiated structural design does not simply use the same specifications for all components, but rather matches them according to the span, height, and load conditions of different areas. By rationally configuring component specifications, structural design requirements are met while avoiding unnecessary material usage, making the overall structure more economical and rational.

Galvanized C-beam Purlins, Balancing Structural Integrity and Durability

The project's roof purlins uniformly use galvanized C-beams. C-beam purlins primarily support the roof cladding system and form a complete structural system with the main H-beam frame.

Galvanizing improves the corrosion resistance of the steel components' surface, reducing maintenance needs during long-term use, making it particularly suitable for warehousing projects with high durability requirements.

Single-Layer Corrugated Steel Sheet Enclosure System

Both walls and roofs utilize single-layer corrugated steel sheets. This solution is lightweight, easy to install, and highly efficient in construction, while meeting the basic enclosure requirements of typical warehouse buildings.

Depending on the overall project function and local environmental conditions, the single-layer metal sheets can be integrated with appropriate roof slopes, flashing, gutters, and sealing joints to form a complete building envelope system.

Complete Building Packages, More Than Just the Main Steel Frame

In addition to the H-beam main frame and galvanized C-beam purlins, Canglong Group also provides complete steel structure kits and building accessories based on the overall project requirements, including:

* Main steel structure

* C-beam purlins

* Support and connection system

* Corrugated steel sheets for roof and walls

* Gutters

* Downpipes

* Doors and windows

* Various connection and installation accessories

This complete package reduces the size matching and on-site coordination issues that arise when customers purchase different materials separately.

One-stop Service From Design to Delivery

The Canadian project had high coordination requirements for structural design, material supply, and overseas logistics.

Canglong Group provided the following services for this project:

Design → Detailed Design → Manufacturing → Material Supply → Quality Control → Kit Assembly → Packaging and Container Loading → Booking and Transportation → Installation Guidance

From the structural design stage, the different areas of the building with varying heights were planned holistically to ensure compatibility between the main steel structure, purlins, cladding system, and building components. Through a one-stop supply model, the client no longer needed to deal with multiple suppliers separately, enabling a more efficient procurement process from design to on-site installation.
