FABRICATION |
|
|
|
|
Bilmat Engineering Private Limited believes in
constantly upgrading the technology at unit to meet the changing expectation of
its customers. We do not believe in cutting corners and compromising on quality.
In order to maintain our leadership in our field we maintain a highly skilled
level of man power along with the latest in manufacturing infrastructure to
ensure our products are of the highest quality.
In order to have quality fabrication, Our Machinery i.e. Power Press, Hydraulic
presses, Machine tools, Jigs and Fixtures ensure that bent items are handled
without distortion. Our strategically positioned cranes (on ground and
overhead), simplify handling of materials without any strain to our employees.
All our machines and tools are equipped to process steel conforming to various
specifications like IS, BSEN, ASTM, JIS & DIN.

GALVANIZING |
|
|
|
6.500m X 1.250m X 0.800m Galvanizing bath
available for galvanizing of Structure Material. Our state of the art Oil -
Fired Hot - Dip Galvanizing Plant, complete with heat pumping unit, flame proof
- type flow heater, self proportioning burner, centrifugal blowers and Heat
resisting cover with pickling, rinsing, pre-fluxing and quenching (running
water) tank and Zinc Kettle, ensures that the finished product confirms to
international standards and is strictly as per IS 2629, IS 4759 and to the
customers requirement. The pretreatment of steel is effectively handled with
chemicals to minimize effluents. The control treatment includes degreasing,
pickling and fluxing for an ideal reaction between Steel and zinc. The
preheating chambers ensure uniform drying and preheating of steel to give an
excellent surface finish and uniform coating of zinc. The temperature of
galvanizing furnace is accurately controlled by digital temperature meter.

Hot-Dip Galvanization
|
|
|
|
|
|
Soil and grease removal
- A hot alkaline solution removes dirt, oil, grease, shop oil,
and soluble markings. Pickling - Diluted solution of sulfuric acid remove
surface rust and mill scale to provide a chemically clean metallic
surface.
|
|
|
|
|
|
Fluxing - Steel is immersed in liquid
flux (a zinc ammonium chloride solution) to remove oxides and to prevent
oxidation prior to dipping into the molten zinc bath..
|
|
|
|
|
|
Galvanizing - The
article is immersed in a bath of molten zinc at between 815-850 F (435-455
C). During galvanizing, the zinc metallurgically bonds to the steel,
creating a series of highly abrasion-resistant zinc-iron alloy layers,
commonly topped by a layer of impact-resistant pure zinc.
|
|
|
|
|
|
Finishing - After the steel is withdrawn
from the galvanizing bath, excess zinc is removed by draining. The
galvanized item is then air-cooled.
|
|
|
|
|
|
Inspection - Coating-thickness and
surface-condition inspections complete the process. The galvanizing
process has existed for more than 250 years and has been a mainstay of
North American industry since the 1890s. Galvanizing is used throughout
various markets to provide steel with unmatched protection from the
ravages of corrosion. A wide range of steel products from nails to highway
guardrail to the Brooklyn Bridges suspension wires to NASAs launch pad
sound suppression system benefit from galvanizing's superior corrosion
prevention properties.
