Shandong Sesame Grey Granite Board Natural Stone External Wall Floor Laying Engineering Material

Description :

  Sesame gray granite is a natural igneous rock material originating from Shandong mining areas, widely used in the field of architectural decoration due to its stable physical properties and classic gray tone. This category mainly solves the needs of outdoor and indoor high wear and weather resistant paving, suitable for typical working conditions such as squares, sidewalks, exterior wall dry hanging, and courtyard landscapes. As a basic building material, sesame grey granite has high density and compressive strength, and can withstand long-term pedestrian trampling and natural weathering erosion. It is one of the mainstream choices for ground laying in municipal engineering and commercial complexes.

  In terms of specifications and craftsmanship, sesame gray granite usually offers various surface treatment methods such as fire burned surface, lychee surface, polished surface, etc., to meet different anti slip and aesthetic needs. The common thickness of the board is 20mm, 30mm, 50mm, and the size can be customized and cut according to the engineering drawings, such as standard modules of 600 * 300mm, 800 * 400mm, etc. This stone complies with the national standard for natural granite building slabs, with a water absorption rate typically below 0.6% and a bulk density greater than 2.7g/cm ³. It has good acid and alkali corrosion resistance. Some high-level products can pass the radioactive A-class certification to ensure indoor safety.

  When selecting, it is necessary to clarify the usage scenario to determine the surface treatment process: for outdoor squares and roads, it is recommended to use burnt surface or lychee surface sesame gray granite to increase the friction coefficient and prevent slipping; Indoor walls or countertops can be polished to enhance glossiness and decorative effect. Attention should be paid to distinguishing between sesame gray and other varieties such as sesame black and yellow rust stone. Sesame gray has a cool gray tone and relatively small color difference, making it suitable for modern minimalist style. If used for load-bearing lanes, it is recommended to have a thickness of no less than 50mm and reinforce the back mesh to avoid breakage due to heavy pressure.

  Before installing sesame grey granite, it is necessary to ensure that the base layer is flat and firm. Special stone bonding agents or cement mortar should be used for paving, and the recommended gap width should be controlled at 3-5mm for jointing treatment. In daily maintenance, surface stains should be regularly cleaned to avoid the infiltration of oily substances causing color spots. For sesame gray granite that has been used outdoors for many years, regular application of protective agents can be carried out to extend its service life. Common faults include alkali bleeding and water spots. During construction, a waterproof isolation layer should be prepared. Minor scratches can be repaired by professional polishing to maintain the overall aesthetics of the stone.

Shandong Qicheng Stone Co., Ltd. was established in 2012. It is a comprehensive stone enterprise that integrates mining, CNC precision production, engineering scheme design, national sales and distribution, and one-stop after-sales support throughout the entire industry chain. For more than ten years, we have been deeply involved in the fields of municipal infrastructure, urban renewal, landscaping, transportation and highways, and real estate supporting stone materials. With stable mining resources, standardized quality control systems, and mature engineering delivery capabilities, we have become the preferred benchmark supplier for domestic stone engineering bidding and bulk procurement in 2026.

The company has a complete industrial layout, built a north-south linkage production system, and has two standardized intelligent processing bases under its jurisdiction, Rizhao Ruijing and Hubei Shenghai. Relying on the core high-quality sesame ash mineral resources of Wulian in Shandong, the company owns multiple primary granite mines. The raw stone reserves are sufficient, the ore veins are stable, and the stone is dense and uniform. Quality problems such as color difference, discoloration, and dark cracking are eliminated from the source, completely solving the industry pain point of unstable quality in large-scale engineering bulk supply. The coordinated operation of the dual base can quickly cover projects in various provinces and cities across the country, efficiently ensuring the implementation of the construction period.

The enterprise has strong software and hardware capabilities and has established a professional engineering service team of 50 people, including 20 senior stone engineers. They have rich experience in key municipal project docking, deepening of irregular stone materials, construction process adaptation, and on-site technical guidance. They can provide professional technical support for engineering projects throughout the process, including drawing optimization, process selection, size customization, and troubleshooting. The entire factory area is equipped with modern intelligent production lines such as infrared CNC cutting machines, fully automatic edge grinders, and fine polishing equipment, achieving standardized assembly line precision production. The daily output of stone materials exceeds 5000 square meters, and the daily output of sesame ash roadside stones can reach more than 5000 meters. It can easily undertake provincial key projects, contiguous urban renewal projects, and large-scale urgent orders.

With a compliant business model, strict quality control standards, stable delivery capabilities, and a good market reputation, the company has successfully been awarded the titles of Advanced Enterprise, Honest Enterprise, and Industry Benchmark Enterprise in the Stone Industry Park in 2026. In order to adapt to the high-end municipal bidding standards and national engineering acceptance specifications, the company has created a unique three color production scheduling management system and three inspection quality control system, covering the entire process of raw material screening, CNC cutting, edge grinding and chamfering, surface process treatment, finished product quality inspection, packaging and outbound closed-loop control, layer by layer verification and strict quality control, ensuring that all factory stone sizes are accurate, corners are regular, strength meets standards, and weather resistance is strong, fully meeting the high standard acceptance requirements of municipal excellence projects.

The company has a complete range of product categories, mainly including sesame ash curbstone, chamfered curbstone, S-shaped curved curbstone, tree pond stone, fire burned board, floor paving stone, exterior wall dry hanging stone, special-shaped carved stone and other engineering stone materials. It supports various non-standard special-shaped, special thickness, special craftsmanship, and exclusive customization of engineering drawings. The entire process is directly supplied by the source manufacturer without any intermediary markup, with outstanding cost-effectiveness advantages. The products are widely used in various engineering scenarios such as municipal road upgrades, sponge city construction, highway transportation support, urban parks and squares, residential communities, commercial streets, waterfront landscape belts, etc.
