How to install PVC formwork for concrete ?

Tip 01: Edge distance of nails/screws to PVC formwork for concrete

To prolong the life-span of PVC formwork for concrete, we suggest to leave at least 3-5cm distance from the edge when nailing/screwing on it. 

Tip 02: Beam distance of PVC formwork for concrete 

In general, we suggest the same beam distances as the plywood formworks which you are using. But, it differs a bit according to the frame structures and concrete thickness. The stronger structures, the shorter beam distance.

Tip 03: Nailing/screwing distance of PVC formwork for concrete

Same as the general requirements for all formwork materials, to ensure the average load-bearing capacity of the entire sheet, in addition to the appropriate props distance, we also recommend maintaining an average spacing of nails/screws, such as 30 cm. Especially the corners should be fixed well with nails/screws. Or you can keep the regular way that applied to your structures. 

Tip 04: Joint treatment of PVC formwork for concrete

If you want to avoid the concrete sticking into the joint, you can paint the joint. The regular painting is workable enough. Some of our clients use the gel coat.

Tip 05:  Repair the holes of PVC formwork for concrete nails or bolts 

For the nails holes: normally such holes don't leak concrete, so not necessary to fix it. If you have strict requirements, you can use glue or wax to cover them. 

For the bolt holes: plastic plug or adhesive tape. Another solution: normally the bolt holes of one single project have same diameters and locations. So some clients cut formworks sheets into small round pieces with 1mm smaller diameter, and then insert them into the bolt holes.

What is PVC formwork for concrete ?

PVC formwork for concrete is new type of plastic formwork material, which is made of Virgin & Pure UPVC only. 

Nowadays, the worldwide trend of environmental protection is being increasing important. Under the background of this trend, PVC formwork for concrete was created by over 10 years ago and got quick development. Recently several years, it's being well-known by tens of countries. 

PVC formwork for concrete a good choice to substitute the traditional formwork materials including plywood /wood formworks, so as to greatly save the forest sources. It has same sizes as plywood, can reuse ≥ 50 times, waterproof, anti-flaming, no need releasing oil, UV resistant, etc.

15 Major Advantages of PVC formwork for concrete:

1. Reuse 50+ times, saving much project costs

JINGFANG® PVC formwork for concrete can be reused ≥50 times in plain wooden structures,  and much more times in metal frames. This means the lifespan of 1 piece of JINGFANG® PVC formwork for concrete equals to ≥ 5~10 pieces of plywood formwork.

2. Same dimensions & applications as plywood/wood formworks 

JINGFANG® PVC plastic formwork has the same dimensions and applications as regular plywood /wood formwork, including applied for wall, slab, column, stairs, tunnel, bridge, etc. 

Its usage in preparing, handling, installation and assembly are same as plywood formwork. No changes to the formwork structure and construction process.

3. No need extra tools and trainings

JINGFANG® PVC formwork for concrete has excellent screw holding strength, can be freely saw, cut, drill, nail, and shaped into any sizes as desired.  

Workers may prepare the JINGFANG® PVC formwork for concrete in the same way as that they use to regular plywood/wood formwork. 

No additional trainings or special tools required for workers to handle the product.

4. Uniform foaming technology, never delaminates

JINGFANG® PVC formwork for concrete adopts the foaming technology, not layerinng or laminating. It will never delaminate even after reusing 50+ times. So it can be reused continually unless it is badly cracked by violent construction.

5. Smooth concrete surface, guarantee project quality

Our mirror surface technology ensures JINGFANG® PVC formwork for concrete smooth surface, and is able to maintain its smoothness even after reusing for 50+ times. This helps ensuring all the wall surface in uniform smoothness across first to top floor.

6. High Load-bearing Capacity

JINGFANG® PVC formwork for concrete has good surface hardness with excellent strength in during high impact. This is another important reason why it can be reused 50+ times in a plain wood support structure.  

7. High Bending Strength and Elasticity 

JINGFANG® PVC formwork for concrete has excellent bending strength. You can curve it freely in your round formwork structure.

Even in winter, JINGFANG® PVC formwork for concretemaintains its elasticity in bending. Non-fragile.

8. Good nails-holding power

Qualified raw material and formulation guarantee the qualified nails-holding power of JINGFANG® PVC formwork for concrete, which is another important guarantee for its ≥ 50 reusing times. The nail holes can be re-nailed form times without cracking or loosing.

9. Anti-flaming, avoiding hidden safety hazards

With pure UPVC as the only main material which accounts for over 95%, JINGFANG® PVC formwork for concrete is anti-flaming without hidden safety hazards. 

This effectively reduces the fire risk and limits the spread of fire.

10. 100% Moistureproof and Waterproof

JINGFANG® PVC formwork for concrete is 100% waterproof. So it is durable enough to be used, stored or placed at outdoor environment without the need of any extra protection, including under the weather of raining, snowy, in Summer or Winter.

11. UV resistant, Chemical Resistant Against Harsh Environment

UPVC is the upgrading of general PVC. It has over 4 times better outdoor anti-aging performance than general PVC,  with lifespan for tens of years. It accounts for over 95% in our product formula, so can guarantee JINGFANG® PVC formwork for concrete the qualified resistance against UV, temperatures and weather. 

12. High Temperature Resistant and Freezing-thawing Resistant

JINGFANG® PVC formwork for concrete has good resistance against temperature. No shrinkage, bulge, or deformation under -25℃ to +70℃ . It can be exposed to any weather, raining or snowy, summer or winter. No need to worry about it being weaken by the sunshine or temperature.

13. No Need Releasing Oil, Easily Releasing and Cleaning 

With sustaining smooth surface and excellent hardness, JINGFANG® PVC formwork for concrete doesn't stick concrete stubbornly, which ensures it to be easily cleaned with water+mop.

No releasing agent or oil is required before and during concrete demoulding process. Easily cleaning.

Easily demoulded by hands, leaving the wall surface smooth and glossy without the need of secondary plastering.

14. 100% Recyclable with Extra Returns
