Is the staircase a DIY installation? Do we still need on-site welding?

The stairs are fixed by locking screws and do not require on-site welding. We will also make corresponding installation instructions for the stairs according to the buyer's requirements. When the buyer receives the goods, they can directly DIY the stairs on site. We can also provide telephone guidance throughout the installation process. If necessary, we can arrange for a master to go to the buyer's local area to guide the installation of the stairs.

AI-Powered supplier vetting

SummaryThe supplier is described as a combined company and a large-scale professional manufacturer of stairs and customized indoor and outdoor decoration hardware building materials, with integrated design, R&D, production, installation, sales, agency, consulting, and service capabilities. It reports five production lines, export experience of ten years, and export sales representing 41%–50% of total sales. Customization and ODM/OEM services are explicitly available, including work for well-known brands and new-product development during the past year. However, service, supplier approval, corrective-action, complaint-handling, and finished-product inspection procedures lack written records. The supplier has no overseas warehouse, showroom, overseas agent or branch, or offline trade-show experience. No SDK is available, and ongoing production quantity reconciliation is not performed.

Supplier typeThe supplier is identified as a combined company and is described as a large-scale professional manufacturer integrating design, R&D, production, installation, sales, agency, consulting, and service for stairs and customized indoor and outdoor decoration hardware building materials. This supports classification as an integrated manufacturer rather than a narrowly focused trading entity.

R&D capabilityThe supplier reports new products during the past year, offers ODM services, and supports customization from samples, designs, minor changes, full customization, and flexible customization. It does not have an available SDK, which is a stated limitation for SDK-dependent development, but the broader R&D and design evidence supports innovation capability.

Production capacityThe supplier operates five production lines and is described as a large-scale manufacturer; stated lead times are one month off-season and two to three months during peak season. However, it does not conduct continuous quantity reconciliation for every batch or mass production, and the evidence does not fully establish production control maturity.

Customization capabilityThe supplier explicitly provides customization from samples, designs, minor customization, full customization, and flexible customization, alongside ODM services and integrated design and R&D capabilities. These directly support a broad customization offering.

Client casesThe supplier explicitly states that it provides OEM services for well-known brands, which is evidence of at least one type of customer engagement. No brand names, project details, product examples, or independently verifiable case documentation are provided.
