The production process of steel and wood keel is different due to different geographical names. Steel and wood keel is referred to as steel clad wood, steel clad wood square, and iron clad wood in some construction projects. The production process of this product is very simple, that is, the wooden square is wrapped with a layer of square steel structure. The steel outside not only protects the wooden square, but also reduces the cost of using turnover materials for the construction unit. The outer square steel is made of hot-dip galvanized square steel pipes, with a wall thickness of 1.0mm-3.0mm. It is customized according to different construction requirements, and the zinc content is 60-80 grams per meter. After double-sided punching and forming, the inner filling material of the square steel is the entire Douglas fir or hemlock pine, and the wooden square has lines on all sides without standard leather joints. The assembly fullness reaches over 96%.

The commonly used specifications and models for steel and wood keels include the following (the thickness of steel pipes can be customized according to construction needs):

40 * 40 * 1.5mm-2.0mm

50 * 50 * 1.5mm-2.0mm

40 * 60 * 1.5mm-2.0mm

50 * 70 * 1.5mm-3.0mm

Eight conventional lengths: 1.5m, 2m, 2.5m, 2.65m, 2.7m, 3m, 3.5m, and 4m (can be processed and produced to a certain length)

Section size: 50mm * 50mm * 1.5mm. Customizable according to construction needs.

Weight per meter: 3.67kg

380 meters per ton of linear meter

Length specifications: Regular 2 meters, 2.5 meters, 2.6 meters, and 3 meters. Customizable according to construction needs. The length can reach up to 4 meters.

This product has two faces and four holes. The four sided holes are mostly used in the internal corners for easy operation and installation.

Comparison between steel and wood keel and wooden square:

If comparing the steel wood keel with traditional wooden batten, the loss is about 1%, and the size error range is relatively small. The important thing is that its flatness is high, so this new type of building material is gradually replacing wood.

2. Traditional wooden blocks are susceptible to climate change, making them prone to deformation and bending during construction.

3. Disadvantages of wooden materials: (1) Due to the fact that they are made of wood, they are prone to corrosion, insect infestation, flammability, and moisture. (2) Wooden materials are prone to cracking and nail holes at the joints.

The purpose and advantages of using steel and wood keel:

Steel wood keel is used instead of traditional wooden square, with high turnover rate and low loss.

1: Overall cost savings of over 60%.

2: Strong universality, suitable for any wall structure, flexible and convenient operation. The use of this type of steel clad wood is even simpler, similar to the use of wooden blocks. Workers can understand it at a glance, and the operation method is the same. The auxiliary keel is directly placed on the main keel, which can achieve manual docking and is easy to get started. This is easy for workers to accept.

3: The turnover frequency reaches 300-500 times, with a high turnover rate and recycling, saving reinvestment.

4: The installation speed is fast, and the construction efficiency is more than three times higher than traditional wooden blocks.

5: It has a large bearing capacity and is made of Q235 carbon steel, which can be freely inserted to meet any size of building area. Building it up, it's not a problem to bear 2-3 tons per square meter. The characteristics of cold rolled steel are high hardness, good elasticity, and toughness, which are not easily deformed.

6: Intuitive and easy to understand, easy to construct and disassemble, and easy to operate without guidance. The roof, wall, and column have high universality and do not require a separate construction plan.

7: Steel beam body with high load-bearing capacity; Using steel instead of wood, there are no consumables, and the cost can be recycled, reducing waste expenses.

8: The use of steel clad wood saves labor, time, materials, and costs. The composition of the steel clad wooden formwork support system mostly adopts the plug and pin type, which is simple and convenient to install and disassemble, and the construction speed is fast. Compared with traditional formwork support technology, it can improve construction efficiency.
