Design Development

At Dezi Construction, the production process begins with comprehensive design refinement. We meticulously enhance designs provided by clients, incorporating meticulous management of CSD, MSD, PSD, and BIM. Our expert team ensures precision and adherence to specifications, guaranteeing the seamless translation of conceptual drawings into tangible, high-quality products. This initial step sets the foundation for the efficient and accurate manufacturing of GRC precast components tailored to meet our clients’ exact needs and specifications.


Prototype fabrication involves creating prototypes tailored to the complexity of product shapes. This process includes subcontracting foam prototypes, 3D printing prototypes, plaster prototypes, and wooden models based on the intricacy of the design.

Each method is carefully chosen to ensure accuracy and efficiency in prototype production, allowing us to assess and refine the design before proceeding to full-scale manufacturing. Our commitment to utilizing diverse fabrication techniques ensures that we deliver GRC precast components of the highest quality and precision.


Mold fabrication

Mold fabrication involves crafting molds tailored to the shape and surface texture of the product. We employ various materials for mold production, such as silicone molds, FRP (Fiber-Reinforced Plastic) molds, plaster molds, and wooden molds, depending on the intricacies of the design.

Each mold material is carefully selected to ensure precise replication of the desired form and texture. Our expertise in mold making allows us to accommodate diverse design requirements and produce high-quality GRC precast components with consistent accuracy and detail.

Production and CURING

After mass production using molds, the products are demolded and undergo post-processing, including repair, polishing, and wet curing. This meticulous process continues until the dimensions, appearance, and quality meet rigorous quality acceptance standards. Our skilled technicians meticulously inspect each GRC precast component to ensure it meets the highest standards of craftsmanship and durability.

This commitment to quality control guarantees that our products not only meet but exceed our clients’ expectations, delivering exceptional performance and aesthetics in every batch produced.

Internal Test

Following quality acceptance, our products undergo rigorous internal testing, including bending test, slump test, wash-out test, bag and bucket test.

These comprehensive assessments ensure that each item meets stringent quality standards, guaranteeing durability, structural integrity, and compliance with specifications.

Our commitment to excellence extends beyond surface aesthetics, prioritizing the reliability and performance of every GRC precast component we deliver.


Our packaging is tailored to each product’s shape and size to ensure safe transport over long distances, minimizing the risk of damage.

Additionally, we provide cost-effective packaging solutions, maximizing container space to accommodate more products per shipment, thus reducing freight expenses for our clients.

This strategic approach not only safeguards the integrity of our GRC precast components during transit but also optimizes logistical efficiency, enhancing overall value for our customers.
