En124 D400 Ductile Iron Access Cover Double Triangle With
Accessories
Product Discription:
Telecom manhole cover is a specialized cover used to enclose
inspection chambers for telecommunications, cables, and fiber optic
pipelines. It primarily serves to protect underground communication
facilities, prevent external damage or interference, and ensure
that maintenance personnel can safely inspect and repair the lines.
We offer various types of telecom manhole covers, such as the LT,
LC, KC, PC, PT, and KE series. Additionally, we can design and
manufacture customized covers according to customer requirements.

Who we are
SND has been producing and selling metal goods for about 20
years.By using manufacturing techniques including sand casting,
lost wax casting, lost foam casting, and precision machining, the
company has been supplying goods made of materials like cast iron,
steel, stainless steel, aluminum, etc. Additionally offered are
surface finishing and assembly services.
Our company has successfully created products in a variety of
industries, including automotive, rail transportation, agricultural
machinery, chemical, energy, electricity, water, air compressor,
and construction, thanks to our consistent efforts over the past
few years.
Our factories' ISO9001-accredited quality control systems guarantee
a consistent and dependable quality for each and every component.
Spectrometer, ultrasonic, magnetic, permeability, elongation,
tensile/yield strength, and other inspections are carried out as
part of routine production procedures.
Manufacturing Process
Material Preparation: High-quality pig iron and scrap iron are
melted together, with magnesium added to create a ductile iron
alloy.
Casting: The molten iron is poured into molds to form the basic
shape of the manhole cover. Sand casting is a common method due to
its precision and efficiency.
Heat Treatment: The cast pieces are treated with heat to improve
strength and flexibility.
Surface Coating: Anti-corrosive coatings are applied to ensure
longevity in various environments.
Quality Control: Each cover undergoes rigorous testing for
load-bearing capacity, tensile strength, and dimensional accuracy
