30-Acre Steel Plant in PH! No Rust for 20yrs 50% Cheaper Bills
Recently, the 30-acre large-scale special-shaped industrial plant project built by Canglong Group for a Philippine customer has completed the final 3D design review, marking the official countdown to the landing of this cost-effective, ultra-durable, and multifunctional customized industrial facility. In view of the hot, humid, rainy, and typhoon-prone environment in the Philippines, as well as the core needs of customers to reduce costs and increase efficiency and use for 20 years, Canglong has achieved a 50% cost reduction and 20-year rust-free industry breakthrough with structural innovation, material upgrades, and full-chain optimization solutions, creating an industrial plant for customers that takes into account both production efficiency and long-term value.
1. Cost Revolution
In the construction of traditional industrial plants, land, material, and construction costs often account for more than 70%. Canglong Group has achieved a breakthrough of 50% cost reduction through the three strategies of lightweight structure, intensive material, and efficient construction.
Lightweight structure: A combination system of H-shaped steel (beams and columns) and C-shaped steel (purlins) is used. H-shaped steel (Q355B material, flange plate 15mm×web plate 8mm) replaces traditional concrete columns with high strength and lightweight characteristics, reducing the weight of a single component by 40% and reducing the foundation cost. C-shaped steel (section height 200mm, thickness 2.5mm) is used as purlins to improve load-bearing efficiency by optimizing the section inertia moment, saving 25% of steel compared to traditional Z-shaped steel.
Material intensiveness: The wall surface adopts the galvanized aluminum metal sheet (zinc layer 180g/㎡ + aluminum layer 20μm) independently developed by Canglong, which has both the anti-corrosion of galvanizing and the weather resistance of aluminum. The material cost per square meter is 15% lower than that of ordinary color steel plates, and there is no risk of rust within 20 years. The roof uses the combination of "sunshine tiles + CL-W840 roof sheet". Sunlight tiles (85% transmittance) meet the natural lighting needs of the workshop, and CL-W840 metal sheet (wave height 54mm, wave distance 210mm) use the buckle-type lock seam process to replace traditional welding, reducing labor and auxiliary material costs.
Construction efficiency: All steel components (H-shaped steel beams and columns, C-shaped steel purlins, CL-W840 roof sheet) are prefabricated in the factory at the Canglong Henan base (error ≤1mm), and only bolt connection and simple assembly are required on site. The construction period is compressed from the traditional 8 months to 3 months, and the labor cost is reduced by 40%.
2. Special-shaped adaptation
The project site is an irregular polygon (covering an area of 30 acres), and it needs to accommodate both the production workshop (including heavy equipment area) and the office area, which puts extremely high requirements on the spatial layout and structural form. The Canglong design team takes function priority and flexible expansion as the principle to create a special-shaped factory with clear primary and secondary and efficient movement lines.
Space partitioning: The overall length is 123.114 meters, the width is 161.427 meters, and the total height is 14 meters. The brick wall (4.2 meters high, MU15 autoclaved lime sand brick) encloses an independent office area (located on the east side of the factory building, with an area of about 2,000 square meters), equipped with floor-to-ceiling windows and ventilation shutters to meet the sound insulation and lighting needs of the office area. The production area (west side) adopts a full steel structure frame with a floor height of 12 meters (from the ground to the bottom of the steel beam), and two 5-ton driving tracks are reserved to adapt to the installation of large-scale brewing equipment/processing machinery.
Special-shaped structure: In view of the irregularity of the site boundary, the steel frame adopts variable-section H-shaped steel and hinged node design. The cross-sectional dimensions of the beams and columns vary with the span (maximum span 24 meters), and the stress distribution is optimized through finite element analysis to ensure structural safety. The CL-W840 roof sheet and sun tiles on the roof are laid with a high center and low surrounding arc slope (slope 2%), which not only meets the drainage requirements (rainwater drainage ≥ 100L/㎡ in heavy rain hours), but also enhances the beauty of the building through visual levels.
Function extension: The entrance of the factory is equipped with a double-leaf sliding door with a canopy (span 6 meters, canopy extension length 2 meters, galvanized steel pipe frame + sun tile top surface), which is both wind and rainproof and ensures the efficiency of forklift traffic. The wall reserves equipment inspection ports (size 1.5m×1m, equipped with waterproof sealing strips) and ventilation shutters (spacing 300mm) to meet the ventilation, heat dissipation and equipment maintenance needs of the production area.
3. No rust in 20 years
The Philippines has a tropical monsoon climate, with an average annual precipitation of 2000-3000mm and air humidity >80%. Traditional color steel plates will rust in 3-5 years. Canglong Group has achieved its promise of 20 years of no rust with the triple barriers of materials, processes and protection:
Material anti-corrosion: All steel components (H-shaped steel, C-shaped steel, CL-W840 plate) are made of hot-rolled substrate, hot-dip galvanizing and electrostatic spraying. The thickness of the zinc layer of the substrate is ≥80μm (far exceeding the 45μm required by the national standard GB/T 13912-2020), and the spraying layer (polyester powder, thickness 80μm) has a salt spray resistance test of ＞1000 hours (equivalent to 10 years of no rust in the coastal environment).
Node protection: The steel component connection adopts Dacromet bolts (surface galvanized layer ≥120μm), with rubber sealing pads to prevent rainwater from penetrating into the node gap. Waterproof glue and self-tapping screws are used to double fix the purlins and roof panels to prevent capillary water penetration.
Easy maintenance: Both galvanized aluminum metal plates and CL-W840 roof panels support partial replacement. To dismantle a single plate, only three self-tapping screws need to be removed (taking less than 10 minutes), and the maintenance cost is 70% lower than that of traditional color steel plates.
4. 3D design implementation
At present, the 3D design of the project has passed the dual verification of BIM+structural simulation of Canglong Group. The BIM model accurately restores every node of the special-shaped steel frame (including variable-section beams and columns, and canopy connection details), and the structural simulation software (PKPM) verifies the structural safety (maximum displacement angle <1/300) under a level 8 typhoon (wind speed 20m/s) and a level 7 earthquake (peak acceleration 0.15g). At the same time, the design file has synchronously output the material list, construction manual, and installation video to ensure that the local construction team in the Philippines can quickly understand and execute.
From cost optimization to structural innovation, Canglong Group has created a new industrial benchmark for Philippine customers with the concept of customer needs as the core and technological innovation as the driving force. This 123-meter-long industrial plant is not only a carrier of production space, but also a vivid footnote to Canglong's Chinese intelligent manufacturing strength. Let overseas customers realize their high-quality, low-cost industrial dreams easily without compromise.
