Specification of manhole cover:

1. Material: ductile iron QT500-7/GG20

2. Grade: B125 C250 D400

3. Loading test: KN125 KN250 KN400

4. Tensile strength: 500 N/2MM

5. Elongation rate: 7%

Usage:

The strength of ductile iron is comparable to the cast steel, and most of them are used in municipal areas to protect the safety of vehicles and pedestrians.

Features of Ductile Iron Manhole cover:

   1. Medium load testing and strength, they have very good toughness and ductility while have a overwhelming advantage on stretch recovery and less noise and lower vibration transmissions. 

   2. Against theft and safety options

 * Zero theft value, reducing potential accident and futher maintenance cost caused by     thieves.

 * Surface anti-slip thread to guarantee safe road condition even in extreme weather.

 * Lock are available as an option mold into the grate to improve the security rate.

 * Non-electricity conduction and non-heat conduction.

3. Light weight

 * Compared with cast iron manhole cover and grates, duction iron are more than 50%       lighter than it.

 * Lighte weight allows more lading per vehicle, more convenient transportation and       economical saving.

 * Allows a safer working condition, which a single worker is enough when installation     without risk of injury.

4. Durable service life

 * More than 30 years service life without crack and color fading, comparing to 5 years of   cast iron.

 * Anti corrosion, water, dust and pets tight, wellsealed prevent poisonous gas leaking     out.

 * Without displacement, freely radio signal passing.

 * Higher and lower temperature tolerance with the range minus 40 degree and plus 200     degree.

 * Wear indicators available when thread depth is in a danger value.

5. Free design

 * You can just offer the photoes or size then we will design it for you because we have our R&D team.

6. Package

 * Iron pallet or wooden pallet or according to customer's requirements.

Q:Do their own cabinets, cabinets hardware where can I buy?
Cabinet hanging yards, preferably hidden style. Handle should be rich, general building materials city is not rich enough, hinge, better. Foot, the kind of adjustable, engineering plastics can. Materials such as fire boards
Q:What do hardware mainly do?
Hardness testing of stamping partsHardness test of stamping materials, its main purpose is to determine the extent of annealing the sheet metal stamping process is suitable for the purchase will be subsequently the stamping process of different types, different requirements of plate hardness level. The aluminum alloy plate used for stamping processing can be tested by Webster's hardness tester. When the material thickness is greater than 13mm, the hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate shall adopt the Vickers hardness tester.
Q:What are door hardware included?
Pipe hinge: also called spring hinge. Mainly used for furniture door panel connection, it is generally required thickness of 16~20 mm plate. Materials include galvanized iron and zinc alloy.
