Hollow Glass Aluminium Glass Swing Door , Aluminium Mosquito Mesh Door

Floor spring door is a kind of embedded door shaft spring or built-in vertical floor spring. The door leaf can be opened inside and outside freely, and the door leaf is in the closed position when it is not touched. Floor spring door is a kind of common door in decoration engineering, which can be opened freely inside and outside.Aluminum Spring Doors

Installation Method:

Use the glass sucker to hold the thick glass tightly, and then hold the sucker to lift the thick glass plate. 2-3 people should lift at the same time. After lifting, the thick glass plate should be inserted into the limit slot at the top of the door frame, and then placed on the bottom bracket, and the installation position should be aligned, so that the edge of the thick glass plate can just seal the stainless steel facing seam of the side frame column.Aluminum Spring Doors
The method of fixing the thick glass on the bottom bracket is as follows: nail a wooden strip on the side of the bottom bracket, which is about 4mm away from the thick glass plate. Then, brush universal glue on the wood strip, and stick the stainless steel plate on the wood. The installation structure of the upper and lower parts of the thick glass plate is shown in figure 5-197. Glass glue is injected into the top limiting groove, the bottom bracket fixing position and the butt joint between the thick glass and the frame column.Aluminum Spring Doors

Swing Doors Types:

Swing doors for freight elevators are the ideal choice when you are faced with tight shaftways and space parameters that do not accommodate sliding door specification requirements. offers you ideal solutions to all of your freight elevator door needs including some of the highest quality swing doors available in the industry. At , every swing door we sell is constructed to meet our highest standards, and quality service and affordable prices are anything but standard.

offers three types of swing doors for freight elevator applications:

Swing Doors - Consist of one panel containing heavy duty half surface ball bearing hinges that are set in a steel channel door buck.
Center Opening Swing Doors - Consist of two panels each panel containing heavy duty ball bearing hinges, which are set in a steel channel door buck.
Slide Swing Doors - Mounted in conjunction with a Swing door with the capability of a full opening, slide and swing open simultaneously.

The main process is as follows

(1) Ingredients: according to the specific alloy grades, calculate the amount of various alloy components, and reasonably mix with various raw materials.

(2) Smelting: the prepared raw materials are added into the smelting furnace for melting according to the process requirements, and the impurities and gas in the melt are effectively removed by degassing and refining.

(3) Casting: under certain casting conditions, molten aluminum is cooled and cast into round casting rods of various specifications through deep well casting system.

2. Extrusion:

Extrusion is a means of profile forming. First, according to the section of the profile product, the mold is designed and manufactured, and the heated round casting bar is extruded from the mold by the extruder. For 6063 alloy, an air cooling quenching process and an artificial aging process are used to complete the heat treatment. Different brands of heat treatable strengthening alloys have different heat treatment systems.

3. Coloring (here we mainly talk about the process of oxidation)

Oxidation: the surface corrosion resistance of extruded aluminum alloy profile is not strong, so anodizing is necessary to improve the corrosion resistance, wear resistance and appearance of aluminum profile. Almost all the High Bay aluminum profiles produced by Janger High Bay aluminum profile factory are oxidized.

The main process is as follows

(1) Surface pretreatment: chemical or physical methods are used to clean the profile surface to expose the pure substrate, so as to obtain a complete and dense artificial oxide film. It can also be obtained by mechanical means.

(2) Anodization: after surface pretreatment, under certain process conditions, anodization occurs on the surface of the substrate to form a dense, porous and strong adsorption Al203 film.

(3) Sealing: the pores of the porous oxide film formed after anodization are sealed to enhance the anti pollution, anti-corrosion and wear resistance of the oxide film. The oxide film is colorless and transparent. By making use of the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film hole, which can make the profile appearance show many colors other than its original color (silver white), such as black, bronze, gold and stainless steel.
