As we all know, insulated hollow metal doors are made of galvanized steel. Although Asico use high-quality material, the appearance of the surface is still unable to reach the standard of direct use. Therefore, we need a layer of paint on the surface of the hollow metal door to make the surface flatter and more in line with the style of the project.
By now you may have heard of the cutting edge technology known as "powder coating." It's a new way of applying color that's vastly superior to good old-fashioned painting. Powder coating is applied using a dry powder that is electrostacically charged to stick to the steel doors, and then cured in an oven, to give a smooth, hard finish that is much tougher than conventional paint.
Qhov zoo ntawm kev siv hmoov txheej rau steel qhov rooj yog:
Smooth nto ntawm insulated hollow hlau qhov rooj:
Ntxiv nrog rau kev ua cov hmoov nplaum, tab sis kuj kom ntseeg tau tias cov hmoov txawm faib, dua li cov xim zoo nkauj txhuam qhov rooj saum npoo yog smoother.
Perfect Durability:
Fire doors are scratch-resistant and thus more durable. Powder coated doors do not rust and have been tested for more than 4,000 hours of salt spray exposure. However, a normal painted fire door. Over time, the paint will crack, the surface will rust, and the door will be extensively damaged. It is difficult to repair manually. If the surface of the hollow metal door is scratched due to an accident, you only need to buy a small bottle of paint to restore the door to its original shape.
Super Adhesion:
Lub qhov rooj hluav taws yuav kho tau tom qab cov hmoov txau. Yog li ntawd, cov xim yuav tsum ruaj khov rau ntawm qhov chaw ntawm lub qhov rooj thiab yuav tsis poob tawm yooj yim.
High corrosion kuj:
Lub thickness ntawm txheej txheej mus txog 35 microns, uas yog 4-10 npaug ntawm thicker dua li cov xim zoo tib yam. Cov hlau hauv qab yog tsis yooj yim corroded, yog li ua rau lub durability ntawm lub qhov rooj.
Zoo heev yooj:
Tsis zoo li cov xim, lub qhov rooj nplooj los yog thav duab npog los ntawm cov hmoov txheej yuav tsis tawg txawm tias nws yog bent, thiab stretch npaum li cas mus txog 100 feem pua -800 feem pua.
Our powder coating is uniformly sprayed in accordance with the RAL color code. For example, insulated hollow metal doors used in hospitals will use white. The school's art room uses bright green, yellow, blue. The factory's escape route fire door is in a conspicuous red.
