Hainan GRC component line How to identify quality? Take a look at the raw material quality control of GRC lines, such as:

1. Alkali resistant glass fiber must be selected as the reinforcement material, sulphoaluminate low alkalinity cement as the bonding material and mixed with suitable aggregates to form the base material. The supplier must provide the above raw material purchase certification procedures.  

2. Enough glass fiber content must be ensured: check the bending strength of GRC decorative parts of the manufacturer in megapascals, and compare with the industry standard.  

3. The thickness of components shall be controlled between 8-20mm, and the thickness shall be uniform. It is strictly prohibited to exceed the thickness.  

4. Reinforcement: the corners and edges of GRC members shall be reinforced with continuous steel wires (or full-length steel bars) no less than Ø 4; GRC members with geometric dimensions greater than 400 mm shall be equipped with reinforcement mesh, with the diameter of reinforcement no less than Ø 6 and spacing no more than 400 mm

5. The factory certificate shall be submitted for line mobilization, which includes:

a) Product mark and quantity;

b) Delivery inspection results;

c) Production date and ex factory date;

d) Name of production unit;

e) Signature and seal of the quality inspection department of the production unit.

Welding installation method of planting reinforcement:

1. Welds: 1 each at an interval of about 600mm in the vertical direction or at least 5-6 per m2, and 1 each above and below every 400mm in the horizontal direction or at least 5-8 per m2.  

2. When splicing GRC lines, longitudinal embedded heat expansion and contraction resistant welding bars must be welded.  

3. Each force point shall be drilled with a φ 6mm drill to plant φ 8mm steel bars, and driven into the wall at an angle of 25~30 degrees downward, with a depth of ≥ 90-100mm. The welding points must be firm without faulty welding; When the wall is shale brick Ф 8. The steel bar shall be fabricated and welded with the embedded parts of the component.  

4. After the components are installed, ① rust prevention treatment shall be carried out for each connecting welding point to prevent corrosion damage. ② The joints, gaps and damages during installation must be repaired. The joints shall be filled and flattened with sealant or special adhesive, crack resistant mortar and other related materials. The joints must be cleaned before the GRC components are caulked. The joints should be paved with steel wire mesh. More about Hainan GRC component 、 Hainan EPS component Please pay attention to the official website of Hainan Jin'ao Garden Sculpture Art Co., Ltd.
