At Mohammad Shaban Maleki Trading Group, we understand that the foundation of any high-quality construction project lies in its raw materials. Iran is home to some of the world’s purest gypsum deposits, and our mission is to bridge the gap between these premium mines and international markets. We specialize in supplying and exporting high-grade Micronized Gypsum and Super Micronized Gypsum, tailored for construction, industrial, and artistic applications.
What is Micronized Gypsum?
Micronized gypsum is produced through a sophisticated milling process where gypsum particles are ground to exceptionally fine sizes. Unlike traditional gypsum, which may contain coarser grains, our micronized product passes through specific sieves (meshes) to ensure uniformity, high purity, and a smooth finish.
Our Product Range: Based on Technical Excellence
Based on our technical portfolio, we offer two primary grades of gypsum suitable for export:
1. Super Micronized Gypsum (Mesh 200)
This is our flagship product for high-end finishing.
- Texture: Extremely fine powder (like flour).
- Whiteness: Exceptional brightness (typically above 90%), reducing the need for painting.
- Application: Ideal for the final layer of plastering (whitewashing), decorative moldings, and intricate architectural details. It requires no sieving at the construction site.
2. Micronized Gypsum (Mesh 100)
A versatile solution for robust construction needs.
- Texture: Fine and consistent.
- Strength: High compressive and bending strength.
- Application: Suitable for the base layer, joinery, and general plastering. It offers a perfect balance between setting time and workability.

Gypsum Analysis & Quality Specifications
Gypsum Analysis & Quality Specifications – Mohammad Shaaban Maleki Trading Company
At Mohammad Shaaban Maleki Trading Company, all gypsum products undergo comprehensive quality control and laboratory testing before export. The analysis includes purity level, mineral composition, mechanical strength, initial and final setting time, moisture content, specific gravity, and all relevant technical parameters.
Our raw gypsum stone is sourced from high-grade deposits and processed into two main quality classifications.
Depending on customer requirements, we can manufacture any type of gypsum according to the requested technical analysis.
This includes construction gypsum, base coat gypsum, finishing gypsum, super fine gypsum, export-grade gypsum, mesh sizes 100–200–300, moisture-resistant gypsum, undercoat gypsum, and gypsum tailored for industries such as drywall systems, casting, molds, and more.
This page provides all standard laboratory analyses offered to buyers in different countries, ensuring they are fully informed about the technical specifications before placing an order.
We hereby present the technical analysis and laboratory test results of the export-grade gypsum produced by Mohammad Shaaban Maleki Company.
According to the results, the tested sample shows excellent purity, whiteness, and setting time, fully complying with international quality standards.
It is also noted that the analysis results and stone types represent different quality grades, and our products are supplied in two main quality levels.
Since gypsum is used for various industrial and construction purposes, production is carried out based on the customer’s requested specifications and analysis, ensuring that the product precisely meets the intended application.
These results confirm our commitment to consistent quality and customer satisfaction in both domestic and international markets.
Thank you for your trust and cooperation.
