When it comes to steel formwork, we may immediately think of cylindrical steel formwork. Next, we will briefly introduce the characteristics and usage of cylindrical steel formwork to those who are interested in this knowledge.

Characteristics of cylindrical steel formwork
First of all, this product has good resistance, impact resistance, high strength, and good wear resistance. In the process of use, the whole board can be poured after being screwed and positioned. According to our understanding, this formwork has the advantages of low cost, light weight, and simple construction.
In addition, when we use this product, 2-3 people can operate it, the forming effect is good, and it has a high turnover rate in a straight direction with only one vertical gap.
Cylindrical shaping steel formwork needs to adjust the straightness with the help of the pull rod (or its support). In short, the pull rod should be angled at 45 degrees to the ground. As for the specific usage process, it can be mainly divided into:
Here, it should be noted that if it is a cylindrical shaping wooden formwork, there is no need to adjust the pull rod to be straight, and its peripheral column mold has matching steel strips.
What are the methods to remove oil from the surface of cylindrical steel formwork?
Alkaline solution deoiling
Using the "saponification reaction", the vegetable oil, animal oil, and alkali that can be saponified in the construction formwork react to produce glycerol and soap that can be dissolved in water. Glycerol dissolved in water can leave the surface of the formwork with water. Soap can further emulsify grease, generate emulsion of water and oil, and achieve the purpose of deoiling. We have prepared a deoiling agent , which works well when cleaned with warm water.
Organic solvent deoiling
Using solvents such as solvent oil, xylene, and other solvents, the oil stains that can be dissolved in the solvent are removed from the bridge formwork. However, the solvent is flammable and easy to pollute the environment.

The standard for checking whether the oil stains and wax have been removed from the surface is to rinse the formwork with water to form a continuous water film. If the continuous water film does not break within 30 seconds, the cleaning work is considered completed. If the dirt and wax are not completely removed, due to different surface tensions, the water film will not be continuous and will break.
What affects the service life of cylindrical steel formworks? How should cylindrical steel formworks be constructed? We will take you through it.
What affects the service life of cylindrical steel formworks?
When using cylindrical templates, use alloy saw blades with more than 100 teeth and a sawing machine with trails for cutting; use a high-speed handheld electric saw for cutting irregularly shaped cylindrical templates; after cutting and punching the cylindrical templates, it is necessary to use special edge sealing paint to close the incisions to avoid deformation of the cylindrical templates due to water absorption.
Also, when nailing or punching on the cylindrical template, it is necessary to cushion it with wooden planks underneath to prevent splitting on the back of the board due to suspension. When in use, pay attention to preventing scratches, collisions, and falls of the metal edges, making sure that the geometric shape and outer appearance are intact.
In terms of storage and maintenance, after disassembling cylindrical steel formworks used for construction, the outer surface should be cleaned thoroughly with a scraper for easy circulation and use. This ensures the proper maintenance and longevity of the formwork in building construction. If cylindrical templates need to be stored for a long time, they should be coated with oil on the outer surface, stacked neatly, and covered with a rain cloth. During transportation and storage, avoid exposing the cylindrical templates to direct sunlight to prevent fading and aging.
On the construction site, cylindrical templates should be stored in flat, dry areas and should not be placed in extremely hot and humid areas.
What should be noted when constructing cylindrical steel formworks?
Personnel who enter the construction site need to wear helmets, and those working at high elevations should fasten safety belts.
When disassembling, the workers should cooperate with each other, work together, and not throw tools when passing them to each other.
When supporting cylindrical steel formworks, ensure that the site is clean and the materials are placed neatly.
A dedicated person should direct the lifting and transfer of the templates, and unauthorized operations should be prohibited.
Environment education for employees should be strengthened before entering the site to increase their awareness of environmental protection.
Strengthen mechanical management and reduce noise during construction.
