We cater to bulk requirements for contractors, wholesalers, and private developers nationwide.

Yes, 5Dragon Construction Corp. is a trusted supplier for public works, national roads, highway drainage systems, and DPWH (Department of Public Works and Highways) infrastructure contracts. Our HDPE Structured Wall Pipes and HDPE Dual Wall Corrugated Pipes are manufactured to meet or exceed SN4 and SN8 ring stiffness specifications. This guarantees they can handle heavy structural underground loads, high soil cover, and dynamic traffic stresses. We regularly supply bulk piping to licensed contractors engaged in national highway widening, municipal storm drainage culverts, and municipal sewage network rehabilitations across the Philippines. All materials are backed by test reports and standard compliance certificates required by DPWH inspectors.

5Dragon Construction Corp. is headquartered at 640 General Luna, Bagong Silangan, Quezon City, Philippines. To ensure seamless material procurement for large-scale projects, we provide nationwide logistics and distribution coverage across Luzon, Visayas, and Mindanao. According to our latest performance indices, our direct-to-site delivery on-time rate stands at 92% in Luzon, 88% in the Visayas region, and 85% in Mindanao. We utilize a robust freight network to deliver bulk pipes, roofing sheets, and structural formwork directly to project job sites, municipal yards, and coastal developments. We accommodate both land deliveries and sea-freight shipping to regional hubs.

While both pipes are manufactured from High-Density Polyethylene, they are engineered for different structural applications. HDPE Structured Wall Pipes (typically SN4/SN8) feature a ribbed external profile and a smooth inner bore, making them ideal for high-depth gravity sewer mainlines, highway culverts, and high-load civil excavations. HDPE Dual Wall Corrugated Pipes, on the other hand, feature a corrugated outer wall and a co-extruded smooth inner liner. This makes them lightweight, highly flexible, and ideal for sub-surface storm drainage, municipal rainwater runoff networks, and agricultural subdrainage where rapid installation and high hydraulic flow capacity are required. Both styles prevent root intrusion and joint degradation.

We supply HDPE pressure pipes across a wide range of Standard Dimension Ratios (SDR) to accommodate varying water pressure requirements. Our main stocking options include SDR 11 (PN 16 pressure rating) and SDR 17 (PN 10 pressure rating), with custom specifications available for large-volume industrial projects. The lower the SDR number, the thicker the pipe wall and the higher the pressure it can safely handle. These pipes are widely used in potable water transmission lines, agricultural irrigation networks, high-pressure industrial pumping pipelines, and sea-water intakes. We offer matching compression fittings and electrofusion couplers for all SDR classes.

Absolutely. 5Dragon's Polypropylene Random Copolymer (PPR) pipes and fittings are specifically engineered for commercial and residential hot and cold water distribution. Because they are manufactured from food-grade raw materials, they are non-toxic, lead-free, and safe for potable drinking water. Our PPR pipes can withstand continuous operating temperatures up to 95°C and high pressure levels, making them the standard choice for central hot water systems in hotels, condominium risers, hospitals, and high-rise office developments. They are connected via heat fusion, creating unified leak-proof pipelines.

Our uPVC Thermoplastic Roofing Sheets offer massive technical advantages over traditional corrugated iron or steel roofs. Firstly, uPVC is completely immune to rust, corrosion, and chemical rot, which is crucial for chemical storage facilities, coastal resorts, and agricultural barns. Secondly, they feature superior thermal insulation properties, reflecting solar heat to keep indoor temperatures up to 5°C cooler. Lastly, the acoustic-damping property of uPVC significantly reduces rain noise, providing a quieter, more comfortable indoor environment. These roofing sheets have a life expectancy exceeding 25 years with minimal maintenance.

PVC-O (Oriented Polyvinyl Chloride) is the latest evolution in plastic piping technology. By stretching the PVC molecular structure during extrusion, the pipe gains double the tensile strength and impact resistance of traditional PVC. This molecular orientation makes PVC-O pipes highly crack-resistant, extremely flexible (capable of absorbing high water hammer shocks), and lighter weight, which reduces logistics and handling costs. They are the ideal choice for high-pressure municipal water mains and regional potable water distribution lines. They increase flow capacity due to their thinner walls and smooth bore.

Yes, our Polypropylene (PP) Formwork Boards are designed specifically for maximum reuse, serving as a cost-effective and eco-friendly alternative to traditional phenolic plywood. While plywood typically warps or splits after 5 to 10 uses, our hollow-core PP formwork boards can be reused 30 to 50 times or more. They are completely waterproof, chemical-resistant, and do not require release agents, leaving a clean, smooth, concrete finish while significantly lowering total project material overheads. They are also easy to clean, saw, and nail on site.
