KAIHUA, China – KaiHua JinXin Building Materials Co., Ltd., a national high-tech enterprise specializing in sustainable paving systems, has been awarded the Sci-Tech Small and Medium-Sized Enterprise Certificate, a recognition granted to enterprises demonstrating strong technological innovation capacity, research and development investment, and commercialization potential in their specialized field. The certification adds to the company's existing credentials as a National High-Tech Enterprise with more than 20 patents, including National Invention Patents for its granite-like permeable bricks and PC bricks, and complements its ISO 9001 quality management system approval.
The company traces its origins to a manufacturing facility established in 2005 and was formally incorporated in 2010. It operates two independently developed fully automated intelligent production lines capable of producing over 1,500 square meters of high-quality permeable pavers and related products daily. Its core product portfolio includes granite permeable pavers, silica sand permeable boards, PC bricks, and complementary paving accessories. Products are manufactured under corporate standards that exceed national requirements, ensuring consistent performance across production batches.
Independent test reports confirm the performance of the company's permeable paving products. For its granite permeable pavers (600mm × 300mm × 60mm, Rf4.5 A-grade), tested under GB/T 25993-2010, the flexural strength averaged 6.2 MPa with a single-unit minimum of 5.7 MPa, exceeding the standard's requirements of 4.5 MPa average and 3.4 MPa minimum. The permeability coefficient measured 2.1×10⁻² cm/s, above the A-grade threshold of 2.0×10⁻² cm/s. Compressive strength averaged 53.3 MPa with a single-unit minimum of 47.5 MPa. For the company's silica sand permeable boards (PF-A 600mm × 300mm × 60mm, Rf5.5 A-grade), tested under the updated GB/T 25993-2023, flexural strength averaged 5.9 MPa with a single-unit minimum of 5.6 MPa, against requirements of 5.5 MPa average and 4.4 MPa minimum. Permeability reached 2.15×10⁻² cm/s, and compressive strength averaged 45.0 MPa with a single-unit minimum of 42.5 MPa.
These performance figures place the company's products within the upper range of the permeable paving market, where specifiers increasingly require documented test data rather than general performance claims. The GB/T 25993 series standard governs permeable pavement bricks and panels in China, and compliance at the Rf4.5 and Rf5.5 A-grade levels is relevant for municipal projects, sponge city construction, and commercial landscape applications where both structural load capacity and rapid stormwater infiltration are required.
The global permeable pavement and pervious concrete pavers market continues its steady expansion, supported by urbanization, stormwater management regulations, and the growing adoption of sponge city concepts in urban planning. China's green building materials policy framework encourages the use of permeable and eco-friendly paving products, and the updated Green Building Materials Evaluation Standard incorporates environmental performance indicators as assessment criteria. Within this context, manufacturers with verified product testing, in-house production control, and recognized innovation credentials are well positioned to serve infrastructure contractors, landscape architects, and municipal developers.
KaiHua JinXin Building Materials Co., Ltd. welcomes inquiries from construction contractors, landscape architects, and infrastructure project developers seeking granite permeable pavers, silica sand permeable boards, PC bricks, and custom paving solutions.
