Technical Specifications & Sourcing Guide

Wholesale Sandstone physical samples from China manufacturer

Sandstone is a porous sedimentary rock, meaning its physical properties dictate its suitability for specific architectural applications. When procuring sandstone in bulk for exterior paving or wall cladding, buyers must evaluate density, water absorption, and compressive strength. Below are the tested physical parameters of our core wholesale sandstone materials.

 

Physical Property Yellow Sandstone Teakwood Sandstone Grey Sandstone Industry Standard (ASTM C275)
Bulk Density (g/cm³) 2.25 - 2.35 2.15 - 2.28 2.40 - 2.55 Min. 2.00
Water Absorption (%) 3.5% - 4.5% 4.0% - 5.5% 1.8% - 2.5% Max. 8.0%
Compressive Strength (MPa) 45.0 - 55.0 38.0 - 45.0 65.0 - 80.0 Min. 28.0
Flexural Strength (MPa) 5.5 - 7.0 4.8 - 6.0 8.0 - 10.5 Min. 2.4
Recommended Application Wall Cladding, Carving Pool Coping, Paving Heavy Traffic Paving N/A

 

Surface Finishes and Architectural Applications

The performance and slip resistance of sandstone heavily depend on the surface finish applied during fabrication. Our factory provides calibrated finishes tailored for specific engineering requirements:

 

Sawn Cut: Delivered directly from the multi-blade gang saw. Provides a high-friction surface (R11 slip rating) ideal for exterior driveways and heavy-duty pedestrian paving.

 

Honed: Mechanically ground to a smooth, matte finish. Reduces pore size, making it suitable for interior flooring and exterior wall cladding where dust accumulation must be minimized.

 

Sandblasted / Bush-Hammered: Treated to create a textured, non-slip profile. This finish is mandatory for wet commercial zones, public plazas, and swimming pool coping to meet international safety standards.

Why Partner with Our Sandstone Factory? (Manufacturing Strengths & QC)

 

Procuring natural stone requires a supplier capable of managing massive volume while maintaining batch consistency. As an established source factory, we operate on hard data and strict industrial protocols:

 

Processing Capacity: Equipped with heavy-duty gang saws, bridge cutters, and multi-head calibration machines, our monthly output exceeds 30,000 square meters. We routinely fulfill phased deliveries for massive commercial projects.

 

Strict Quality Control (QC): We enforce a dry-lay inspection protocol for all custom cut-to-size orders. Our inspectors use digital calipers to ensure thickness tolerances remain within ±1.5mm for sawn tiles and ±3.0mm for natural cleft finishes.

 

Color Variation Management: Sandstone has natural variations. We sort and grade all tiles by base color and vein movement prior to crating, ensuring your installers receive a consistent blend for large surface areas.

 

Export Standard Packaging: All finished products are packed in heavily reinforced, fumigated wooden crates suitable for ocean freight, utilizing internal foam buffering to prevent edge chipping during transit.

Frequently Asked Questions

Q: What is the standard Minimum Order Quantity (MOQ) for your sandstone products?
A: Our standard MOQ is one 20-foot Full Container Load (FCL). Depending on the thickness (e.g., 20mm, 30mm, or 50mm cobbles), a standard container can hold between 300 to 450 square meters of sandstone.
 
Q: Does your sandstone require sealing before or after installation?
A: Yes. Due to the natural porosity of sandstone (water absorption ranging from 2% to 5%), we highly recommend applying a penetrating silane-siloxane sealer immediately after installation and grouting to prevent water ingress and organic staining.
 
Q: Can you manufacture custom architectural elements like balusters, columns, or pool coping?
A: Yes. Our facility includes a specialized profiling workshop equipped with CNC routers and manual carving stations. We can process complex architectural components based on your provided AutoCAD (.dwg) drawings.
 
Q: How do you handle thickness tolerances for natural split-face sandstone?
A: For natural split finishes, thickness cannot be exact. The standard industry tolerance we maintain is ±3mm to ±5mm depending on the exact material. For calibrated back panels, we can achieve a tighter tolerance of ±1.5mm.
