What is the typical Minimum Order Quantity (MOQ)?

Because Z Purlins are produced from steel coils via roll forming, the MOQ is usually based on coil size, typically 20-25 Metric Tons (roughly one 20ft or 40ft container load). Smaller sample orders are possible but incur higher machine setup fees.

Are Z Purlins suitable for Solar Panel Mounting Systems?

Yes. Due to their high strength-to-weight ratio and ability to overlap for long lengths, Z-section rails are very popular in ground-mounted solar farms and large commercial rooftop PV systems, often referred to as Z-mounting rails.

AI-Powered supplier vetting

SummaryJucai Huixin appears to be a photovoltaic bracket and related metal-structure supplier with broad customization and OEM/ODM capabilities. It reports multiple management and product certifications, including ISO9001, ISO14001, ISO45001, CE and RoHS. Production indicators are substantial, with more than 10 production lines, over 30 quality-control staff, and stated solar-bracket output of 1,000,000 tons. The supplier exports primarily to South America, Southeast Asia/Middle East, Europe and North America, with 71%–90% of sales from exports and self-operated import/export rights. It offers installation, training, repair, maintenance and debugging, but reports no overseas warehouse, showroom, agent or branch. Financial records are referenced for 2022–2024, but no financial results are provided. Innovation evidence is mixed: new products were reportedly developed in the past year and ODM is available, while no SDK is available and total R&D-engineer experience is listed as one year.

Supplier typeThe supplier is presented as a manufacturer and seller focused on photovoltaic mounting systems, including hot-dip galvanized, zinc-aluminum-magnesium coated, aluminum alloy and stainless-steel brackets and accessories. Its registered business scope also covers metal structures, mechanical equipment, construction reinforcement products, wires, cables and hardware, indicating a broader industrial materials scope.

CertificationsThe supplier states that its products and management systems have passed ISO9001, ISO14001 and ISO45001 certifications, as well as CE and RoHS certifications. These explicitly documented certifications support compliance and quality-system capability.

R&D capabilityThe supplier reports that it had new products during the past year and provides ODM services, while also offering multiple forms of design customization. Countervailing evidence includes no available SDK and total R&D-engineer experience listed as one year; therefore, innovation activity is demonstrated but technical depth is not fully established.

Production capacityThe supplier reports more than 10 production lines, annual solar-bracket output of 1,000,000 tons, and 31–40 quality-control staff. It also states average peak- and off-season lead times within 15 working days, providing explicit evidence of substantial production capacity and organized quality control.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization and flexible customization. It also reports both OEM service for well-known brands and ODM service, indicating broad product-development and customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of brand-customer experience. No customer names, project details, order scope or independently verifiable case studies are provided.

Product Q&A

Q:What is the difference between Z Purlins and C Purlins?

The primary advantage of Z Purlins is their Z-shape profile, which allows them to overlap at supports, creating a stronger, continuous span ideal for long-span roofing. Z purlins are stronger when oriented correctly, whereas C Purlins are typically used for wall girts or shorter spans where overlapping is not required.

Q:Why should I choose Hot-Dip Galvanized (HDG) Z Purlins?

HDG provides a thick, durable zinc coating that protects steel from rust, especially in humid, coastal, or industrial environments. It lasts significantly longer than paint or pre-galvanized coatings. Unlike painted surfaces, galvanized steel is self-healing at cut edges and requires virtually no maintenance.

Q:What do the dimensions mean (e.g., Z200 x 75 x 20 x 2.5)?

These numbers refer to cross-sectional dimensions: 200 mm is the web height, 75 mm is the flange width, 20 mm is the lip size for rigidity, and 2.5 mm is the material thickness.

Q:Can Z Purlins be used for walls?

While primarily designed for roofing due to their overlapping strength, Z Purlins can be used for walls. However, C Purlins are generally preferred for walls (girts) because they are easier to install without the need for complex overlapping at joints.

Q:How are Z Purlins connected and installed?

Z Purlins are fixed to main rafters using bolts and cleats. To join two pieces for a long span, splice plates must be used at the overlap point to ensure structural integrity.
