Sectional Overhead Doors with PVC Curtains: The Ultimate Solution for Acid Pickling Room Protection

Pickling room as a key place for treating metal surface oxides in industrial production. Its internal environment is often accompanied by the volatilization and splashing of acidic substances, which will make ordinary door panels and metal fittings rust and deform quickly. The service life and stability of industrial doors made of conventional materials will be greatly affected in such an environment. In response to this industry pain point, industrial sectional overhead doors with PVC curtains on the inner layer provide an efficient solution. In this article, we will introduce why industrial sectional overhead doors with PVC curtains are ideal for pickling rooms.

Three Major Challenges of Traditional Industrial Doors in Acid Pickling Room

Materials are not corrosion-resistant

Traditional pickling room doors are mostly common iron doors, and although their surfaces are sprayed with anti-rust paint to try to resist corrosion, the actual results are not as good as they could be. Pickling room in the pickling water has a strong corrosive, even with anti-rust paint protection, but also can easily penetrate, just a few months, the door plate will appear one after another rust spots. The edges of the door and the welded seams of these parts is a corrosion of the“hardest hit”, rust stains are common, seriously affecting the overall performance and appearance of the door.

Insufficient sealing

In the traditional pickling room door structure, door seams and hinge seams are often difficult to achieve a tight fit, which makes pickling water can easily penetrate from these gaps. Once the pickling water into the internal hinges and screws will be in a long time in the humid and full of corrosive substances under the harsh environment, will soon rust, which will lead to the door body jamming phenomenon. It is extremely difficult to open and close the door, which brings great inconvenience to daily use.

High maintenance cost

Due to the problems of corrosion resistance and poor sealing. Make the pickling room door needs frequent maintenance. Basically, every six months, we have to replace the door plate or related accessories for repair. And each maintenance involved in labor costs, material costs and other costs stacked up, a year down, the enterprise at least to spend 2-3 million yuan more for this. This is undoubtedly a considerable expenditure, aggravating the burden of the operating costs of enterprises.

How PVC Curtains Protect Sectional Doors from Corrosion in Pickling Room

In extreme environments such as pickling rooms, the durability and protection of industrial sectional doors is crucial. PVC curtains, as a key component of sectional doors, not only effectively isolate equipment from the outside environment, but also offer a range of unique advantages. The following details how PVC curtain layers can provide extra protection for sectional doors, extending equipment life and improving productivity.

Adding an internal PVC curtain protection layer

In order to further minimize the chances of pickling water coming into direct contact with the inner door panels and hinges of the sectional door, we have added an extra layer of PVC flexible curtain to the interior of the sectional door. This pvc flexible barrier can block the splashing liquid and part of the acid mist in the first step. It is equivalent to adding a “preventive protection” for the sectional lifting door body, which helps to prolong the use cycle of stainless steel door plate and hinge. This not only protects the structure of the door body, but also extends the service life of the door and reduces maintenance and replacement costs.

Abrasion Resistance and High-Temperature Resistance

The working environment in a pickling room is not only harsh, but also accompanied by the entry and exit of people. sectional doors can be customized with pedestrian doors to increase ease and efficiency of access. In addition, the PVC material is highly resistant to abrasion and high-temperature resistance, and can effectively withstand these extreme conditions. the PVC window ply keeps the surface less prone to damage through its high abrasion resistance and reduces friction wear and tear on the door body. These advantages make PVC window coverings ideal for protection in high-intensity environments such as pickling rooms.

Insulation and Heat Resistance

In addition to corrosion and heat resistance, PVC curtains also provide excellent thermal insulation and heat retention properties.PVC curtains effectively block outside temperature disturbances and maintain a constant temperature in the workshop. By reducing temperature fluctuations, PVC curtains help factories save energy by retaining heat in the winter and reducing cold air loss in the summer. For many factories, temperature control not only affects the stability of the production process, but also reduces energy costs.

As we have seen through this article, PVC+ sectional door has demonstrated excellent performance in pickling room environments. Its corrosion resistance makes it effective against pickling water, protects the door body and hinges from chemicals, and reduces the need for equipment breakdowns and repairs. Overall, the innovative combination of industrial sectional overhead doors and PVC is ideal for metal fabrication industries such as pickling rooms.
