Daiwa Color Pipe is a galvanized steel pipe finished with a polyester resin coating on both the inner and outer surfaces, designed for construction, scaffolding, greenhouse, and agricultural structures exposed to moisture. This FAQ guide answers the questions procurement teams ask most often when buying Daiwa Color Pipe: dimensions and customization, minimum order quantity, pricing and lead time, certifications and documentation, and safe handling on site.
Each section is written to support a purchasing decision, so your team can move directly from evaluation to a request for quotation.
What Should Procurement Teams Verify in Daiwa Color Pipe Specifications?
Before ordering, confirm three things: dimensions that match your connectors and drawings, a coating structure suited to your operating environment, and documentation that satisfies your internal quality audit. The subsections below cover each point.
Standard Dimensions and Customization Options
Dimensional consistency matters because scaffolding joints, couplers, and automated cutting tools require tight tolerances. Typical outer diameters for Daiwa Color Pipe cover the common structural range of approximately 19.1 mm to 50.8 mm, with wall thicknesses of roughly 1.2 mm to 2.0 mm depending on pipe size.
Always confirm the current dimensional lineup against the official catalogue or data sheet before finalizing drawings. Custom lengths and sizes can be reviewed against client blueprints for volume orders, so include your drawings with the RFQ if your design uses non-standard dimensions.
Coating Structure and Environmental Durability
Daiwa Color Pipe combines a galvanized zinc layer with a polyester resin coating applied inside and out. The resin layer seals the zinc substrate away from moisture and oxygen, which is why it resists corrosion better than standard galvanized pipe in humid environments - a result confirmed in Daiwa’s own corrosion testing.
This makes the product suitable for greenhouses, outdoor frames, fences, handrails, and coastal structures where condensation, rain, or salt-laden air would degrade ordinary zinc coatings over time. Actual service life depends on site conditions, so describe your environment - humidity, chemicals, coastal exposure - when requesting a quotation.
How Do Ordering, Pricing, and Lead Times Work?
Daiwa Lance International sells directly from its factory in the Tan Thuan Export Processing Zone, Ho Chi Minh City, Vietnam, with a minimum order quantity of 50 pipes and free samples available for evaluation. The points below cover what procurement teams need for budgeting and scheduling.
Minimum Order Quantity and Samples
The MOQ starts at 50 pipes, which allows procurement teams to run a pilot order before committing to high-volume contracts. Free samples can be requested for material evaluation and fit testing against your existing couplers and fittings before any purchase order is issued.
Pricing and Bulk Purchasing
There is no fixed public price list; pricing is quoted per RFQ based on dimensions, volume, and destination. Buying directly from the factory in bulk lowers the per-meter cost compared with purchasing through local distributors, and framework agreements covering multiple quarters help shield project budgets from steel market volatility.
To receive an accurate quotation quickly, include the following in your RFQ:
- Outer diameter, wall thickness, and length for each line item
- Quantity per size, and expected annual volume if repeat orders are planned
- Destination port and target delivery schedule
- Required certifications, inspection records, or test documentation
- Application context (greenhouse, scaffolding, fencing, racking) so the technical team can flag fit issues early
Lead Time, Shipping, and Export Documentation
Lead time depends on order volume and the current factory schedule, so request a confirmed production and shipping estimate at the quotation stage. Daiwa Lance exports to more than 52 countries and handles export documentation - certificates of origin, fumigation certificates, and packing documentation - to reduce the risk of border delays.
Cargo is packed to keep pipes dry and protected in transit. For long-running projects, align delivery windows with your installation schedule and plan a small safety stock with scheduled restocking, rather than relying on urgent spot orders. A clear restocking plan with confirmed lead times is the practical safeguard against project delays.
Which Certifications and Documents Accompany a Shipment?
Daiwa Color Pipe is manufactured under ISO 9001 and ISO 14001 certified management systems, with JIS certification for the factory’s steel pipe production. The product is made using Japanese-derived technology and high-quality materials from Japan.
For corporate quality audits, procurement teams can request the documentation package with each shipment: dimensional inspection records, material documentation, and certified copies of the ISO 9001, ISO 14001, and JIS certificates. Verifying these credentials up front shortens supplier approval cycles and avoids compliance findings after the material has already arrived on site.
Where Is Daiwa Color Pipe Used, and How Is It Fabricated?
Daiwa Color Pipe is used where structures face moisture and need a clean, high-visibility finish. Common applications include:
- Greenhouse frames, winding shafts, and agricultural structures exposed to constant condensation
- Fences, handrails, and outdoor or coastal installations
- Warehouse racking, storage frames, and indoor partitioning in humid facilities
- Scaffolding and structural framing where a durable coated finish reduces maintenance
For fabrication, follow approved welding and bending guidelines so field joints do not become corrosion entry points: strip the coating locally before welding, use low-heat joining methods, and restore the protective layer after the joint cools. Compared with standard galvanized pipe, the polyester resin layer adds a non-porous barrier and better scratch resistance during site handling, which reduces long-term maintenance and replacement costs.
Safety and Structural Reliability Standards
Color pipe is installed in scaffolding, greenhouse frames, and handrails where people work on or around the structure, so product quality is directly a safety matter. Daiwa Lance enforces quality controls at every production stage:
- Reliable seam welds – consistent seam welding prevents splitting under load or thermal stress in the field.
- Clean, oil-free surfaces – inner and outer surfaces are kept free of oils and residues, supporting safe handling and stable coating adhesion.
- Uniform wall thickness and straightness – tight thickness control keeps each pipe straight and rigid, so frames and scaffolds do not bend or snap under working loads.
- Strict quality control under ISO 9001 – every batch is inspected under a certified quality management system before shipment.
- Certified quality and environmental management – ISO 9001, ISO 14001, and JIS certifications back the consistency of every production run.
FAQ – Procurement and Technical Questions About Buying Daiwa Color Pipe
Does the polyester resin coating on Daiwa Color Pipe crack during cold-forming or mechanical bending?
No, not under standard fabrication conditions. The resin layer bonds to the galvanized substrate and has enough elasticity to follow the steel through standard industrial bending and minor fabrication without peeling or cracking. Use smooth forming dies and follow the recommended bending guidelines to keep the coating intact.
How does Daiwa Color Pipe reduce long-term maintenance costs?
By reducing corrosion-related repairs and replacement. Standard steel tube in humid or chemically active areas needs periodic rust remediation or early replacement. Because Daiwa Color Pipe carries polyester resin coating inside and out over a galvanized layer, it seals the steel from moisture and oxygen, extending service life and lowering ongoing maintenance overhead.
Can procurement teams request custom colors for factory safety zoning?
The standard finish is a high-visibility white, which suits brightness and cleanliness requirements in commercial and agricultural structures. Custom color matching can be reviewed for large-volume contract orders — coordinate with the technical team during the RFQ stage if your plant zoning plan requires specific colors.
What storage precautions maximize durability before installation?
Store uninstalled bundles in a dry, ventilated warehouse and keep them off wet ground. Although the coating performs well in moist environments, preventing water from pooling between tightly stacked tubes protects the factory finish until installation begins.
What documentation accompanies a standard shipment of Daiwa Color Pipe?
Shipments can be accompanied by dimensional inspection records, material documentation, and certified copies of the factory’s ISO 9001, ISO 14001, and JIS certificates. Export paperwork such as certificates of origin and fumigation certificates is handled by Daiwa Lance’s logistics team.
