Phenolic Face Plywood

Red construction formwork, also known as red-faced construction formwork or phenolic mirror construction formwork, is a type of formwork with multiple advantages. Its surface is coated with melamine waterproof adhesive, giving it a red color, while the core of the board is made from various wood materials such as poplar, pine, or eucalyptus, making the formwork itself relatively lightweight and easy to use. Red formwork is processed using the hot-pressed plywood method, generally with a thickness of 1.2-1.6 cm, suitable for typical concrete projects such as house construction and the ground floors of buildings. As an upgraded product of red construction formwork, phenolic mirror formwork offers more advanced features. It uses higher-grade phenolic glue, providing better waterproofing and a smoother surface, making demolding easier. Its number of uses is similar to that of red-faced construction formwork, but compared to black formwork, the number of uses is generally 2-3 times fewer.

1. Similarities between red and black construction formwork :

Both red and black construction formwork are supporting structures in construction, and they serve the same purpose. The construction formwork used in cast-in-place concrete projects mainly consists of three parts: panels, supporting structures, and connectors.

(1) The panel is the load-bearing board that directly contacts the newly poured concrete.

(2) The supporting structure is a temporary structure that supports the panel, concrete, and construction loads, ensuring that the construction formwork is firmly assembled without deformation or damage.

(3) The connectors are used to join the panels and supporting structures into a unified whole.

2. Differences between red and black construction formwork:

(1) The most obvious difference is the color: one is red, and the other is black, making them easy to distinguish. Black construction formwork is also called film-faced board.

(2) Red is usually painted with pigment, while black is coated with enamel-like paint. There is a significant price difference; comparatively, black formwork is slightly better. In practice, the black formwork has a glossy surface in contact with concrete, while the red one is rough. Selection depends on quality requirements.

(3) In terms of performance, with equal quality, the red board can be used 2–3 times less than the film-faced board. In terms of pricing, red boards of the same quality are 1 yuan per square meter cheaper than film-faced boards. In practice, the usage rate of both types is still nearly the same. Both types are typically sized 2440mm x 1220mm and 1830mm x 915mm, with the 1830mm x 915mm size being more commonly used.

Precautions for Storing Construction Formwork

1. When storing or transporting construction formwork, care must be taken to avoid impacts, scratches, or drops, as these can affect the product's functional quality.

2. When storing, the environmental conditions required for the product must be met. For stacking two pieces of the product, the boards should be placed facing each other. When stored at construction sites, certain anti-tilt measures should be taken, and they should not be placed leaning against walls.

3. If there is no supporting object during storage, a dedicated stacking rack should be used. The formwork should not be placed directly on other construction materials to prevent tipping over.

4. Construction formwork should not be stored in overly humid environments to avoid cracking or mold due to moisture. Additionally, transport personnel should not throw or drop the materials to prevent damage to the internal or surface quality of the product.

1. Inner packing: Inside pallet is wrapped with a 0.20mm plastic bag.
2. Outer packing: Pallets are covered with 2mm package plywood or carton and then steel tapes for strengthening.
3. Delivery Time: 7~20 working days after payment, we will choose best speed and reasonable price.
