GRC & UHPC Concrete Bench Production Process

Written by: dk@szduke.com Published:2026-7-3

GRC and UHPC concrete benches are widely recognized as high-performance landscape seating for parks, commercial plazas, real estate projects and public outdoor spaces. With excellent durability, weather resistance and artistic shaping ability, they have become the preferred choice for modern landscape design. Our standardized production process ensures stable quality, precise shape and long service life for each bench.

1. Design & Mold Making

According to drawings, design effects and site requirements, we make high-strength silicone or steel molds. Precise mold production ensures consistent size, smooth lines and perfect presentation of special-shaped and curved designs.

2. Material Mixing

For GRC (Glass Fiber Reinforced Concrete), we mix high-grade cement, quartz sand, alkaline-resistant glass fiber and admixtures to ensure high toughness and crack resistance.

For UHPC (Ultra-High Performance Concrete), we use ultra-fine cement, quartz powder, steel fiber and high-performance additives to achieve ultra-high strength, density and durability.

3. Casting & Vibration Compaction

The mixed material is poured into the mold evenly. High-frequency vibration is used to eliminate internal bubbles, making the structure denser, reducing pores and ensuring strong load-bearing capacity.

4. Curing & Demolding

The product is cured under constant temperature and humidity to reach sufficient initial strength. After demolding, the blank is complete and free of damage.

5. Trimming, Polishing & Repairing

Workers trim excess edges, repair small defects, and polish the surface to achieve a flat, delicate and even texture.

6. Surface Treatment & Sealing

We provide natural concrete finish, colored finish, matte or glossy surface treatment. A layer of waterproof and anti-fouling sealant is applied to enhance weather resistance, prevent water seepage, fading and staining.

7. Quality Inspection & Packaging

Each bench undergoes strict inspection including dimensional accuracy, surface quality, structural strength and flatness. Standard export packaging ensures safe long-distance transportation.

With professional technology and strict quality control, our GRC and UHPC concrete benches feature high strength, crack resistance, freeze-thaw resistance and low maintenance. They perfectly combine practical functions and modern landscape art, suitable for long-term outdoor use.
