SummaryQingdao Showhoo Steel Structure Co., Ltd. is identified as both a trading company and manufacturer/factory in China, with stated capabilities covering steel-structure design, manufacturing, overseas installation, maintenance, training, and after-sales support. It provides 3D software design and multiple customization modes, including design- and sample-based customization. Reported production capacity is 10,000 tons of steel structures and 300,000 meters of corrugated steel sheet annually. The supplier offers overseas-agent or branch support and overseas services in Ghana, but has no overseas warehouse or showroom and has not participated in offline trade shows. No new products were launched in the past year, and the available information does not establish certifications, customer cases, raw-material traceability, or clearly defined complaint-handling performance. Financial records are referenced for 2021–2023, but their results are not provided.

Supplier typeThe supplier is described as a comprehensive steel-structure company and is classified as both a trading company and manufacturer/factory. Its stated scope includes steel-structure engineering, prefabricated-house installation, steel-related wholesale, design, manufacturing, overseas installation, and after-sales services.

After-Sales capabilityThe supplier states that it provides after-sales services, while its overseas service offerings include repair, maintenance, debugging, equipment installation, and training, with Ghana identified as a service country. A corrective and preventive action procedure with followed records is reported, although complaint-handling capability is recorded only as “Others” without specific performance evidence.

R&D capabilityThe supplier is identified as a professional technical supplier, provides 3D software design and ODM services, and supports several forms of customization. However, it launched no new products in the past year, has no available SDK, and is marked as lacking R&D capability with product information, so evidence of ongoing product innovation is limited.

Production capacityThe supplier states annual capacity of 10,000 tons for steel structures and 300,000 meters for corrugated steel sheet. Its company description and business scope also cover steel-structure manufacturing and engineering, providing explicit evidence of production capability.

Customization capabilityThe supplier offers flexible, minor, and full customization, including customization from customer designs and samples, and states that it can provide solutions according to customer ideas and requirements. This directly supports a broad customization capability for steel-structure products and buildings.
