industrial park construction project

1.Project Background

 

Located in Southeast Asia, the Philippines is a tropical country with high temperature, heavy rainfall, and high humidity all year round, accompanied by frequent salt spray in coastal industrial areas.

This harsh tropical climate puts extremely high requirements on the corrosion resistance and durability of building materials, especially for industrial roofing structures that need long-term exposure to the outdoor environment. The project is an industrial park construction project in the Philippines, involving the roofing construction of multiple factory workshops and supporting facilities.

As a professional galvalume coil supplier, GNEE STEEL was entrusted to provide high-quality galvalume steel coil for roofing to ensure the stability and service life of the industrial roofing system.

 

2. Customer Needs & Procurement Pain Points

The customer is a local construction contractor in the Philippines, mainly responsible for the construction of industrial park projects. Their core demand is to purchase high-performance galvalume steel coil suitable for tropical climate industrial roofing, which can meet the long-term use needs under harsh environmental conditions. The key procurement pain points are as follows:

 

Poor corrosion resistance of ordinary roofing materials: The high humidity, heavy rainfall and salt spray in the Philippines easily lead to rust and damage of common steel roofing materials, which shortens the service life and increases maintenance costs.

 

Insufficient adaptability to tropical climate: Ordinary steel coils have poor heat resistance, and the roof surface temperature is too high in the hot tropical weather, which affects the internal environment of the workshop and increases energy consumption.

 

Strict requirements on delivery time: The project construction period is tight, and the customer needs to receive the goods on time to avoid delaying the roofing construction progress.

 

High requirements on processing performance: The galvalume steel coil needs to be processed into galvalume roofing sheet on site, which requires good bending, stamping and roll forming performance to ensure smooth construction.

Standard: ASTM A792 / EN 10346 (complying with international standards, ensuring product quality and compatibility with global construction requirements)

 

4. Solutions

Aiming at the customer's pain points and project characteristics, GNEE STEEL provided a one-stop solution for galvalume steel coil for roofing, covering product quality, packaging, delivery, testing and processing, to fully meet the project needs:

 

Packaging Solution: Adopted double-layer moisture-proof packaging, with waterproof paper as the inner layer and galvanized steel sheet as the outer layer, plus side guards and seven steel strips for fixing. This packaging can effectively prevent moisture, rust and collision during transportation, ensuring that the product surface is intact when arriving at the project site, which is especially suitable for the humid climate of the Philippines.

 

Delivery Solution: Optimized the production and logistics schedule, gave priority to arranging the production of the customer's order, and cooperated with professional international shipping companies to ensure that the goods were delivered within 25 days after the order was confirmed, which fully met the customer's construction period requirements.

 

Testing Solution: Conducted strict quality testing on each batch of galvalume steel coil before delivery, including coating thickness test, corrosion resistance test (salt spray test), mechanical property test and surface quality inspection. A complete test report was provided to the customer to ensure that the product quality meets the standard and the requirements of GL coil for tropical climate.

 

Processing Performance Guarantee: The selected DX51D+AZ grade galvalume coil has excellent processing performance, which can be smoothly processed into galvalume roofing sheet through roll forming, bending and stamping. GNEE STEEL also provided professional technical guidance to the customer's on-site processing team to solve potential processing problems in advance.

5. Export & Transportation

In order to ensure the safe and timely delivery of the goods, GNEE STEEL made careful arrangements for export and transportation:

 

Export Port: Shanghai Port (a major international port with convenient transportation, complete supporting facilities and fast customs clearance efficiency, ensuring smooth export of goods)

 

Container Type: 20ft standard container (according to the quantity of goods and product specifications, the container is reasonably loaded to maximize space utilization and reduce transportation costs; the container is also equipped with moisture-proof desiccant to further enhance moisture-proof effect)

 

Moisture-Proof Packaging: On the basis of the double-layer packaging mentioned above, each coil of galvalume steel coil is wrapped with a moisture-proof film, and the gap in the container is filled with moisture-proof materials to avoid moisture damage to the product caused by sea transportation and tropical humid environment, ensuring that the product arrives in good condition.

6. FAQ

Q: Why choose galvalume steel coil for roofing in the Philippines?

A: The Philippines has a tropical climate with high temperature, high humidity and frequent salt spray. Galvalume steel coil has excellent corrosion resistance (the service life is 2-4 times that of ordinary galvanized steel), good heat reflectivity (can reduce the roof surface temperature by 6-8℃) and strong adaptability to tropical climate. It is the most suitable material for industrial roofing in the Philippines. As a professional galvalume coil supplier, GNEE STEEL can provide products that fully adapt to local environmental conditions.

 

Q: What are the advantages of AZ150 galvalume coil compared with other coating specifications?

A: AZ150 galvalume coil has a coating weight of 150g/㎡, which is a medium-to-high grade coating specification. It has better corrosion resistance than AZ100 and other low-coating specifications, and can better adapt to the harsh salt spray and humid environment in the Philippines. At the same time, it is more cost-effective than AZ200 and other high-coating specifications, which can help customers reduce procurement costs on the premise of ensuring product performance.

 

Q: Can galvalume steel coil be processed into galvalume roofing sheet on site?

A: Yes. The galvalume steel coil provided by GNEE STEEL has excellent processing performance, which can be smoothly processed into various types of galvalume roofing sheet (such as sinusoidal and trapezoidal profiles) through roll forming, bending and stamping. We also provide professional technical guidance to ensure the smooth progress of on-site processing.

 

Q: How long is the delivery time of galvalume steel coil from GNEE STEEL to the Philippines?

A: Generally, the delivery time is 25-30 days after the order is confirmed. We will optimize the production and logistics schedule according to the customer's order quantity and construction period requirements to ensure that the goods are delivered on time. For urgent orders, we can also arrange priority production to meet the customer's construction needs.

 

Q: Is GNEE STEEL a reliable galvalume coil supplier for tropical climate projects?

A: Yes. GNEE STEEL has rich experience in supplying galvalume steel coil for tropical climate projects.
