Bitumen (Asphalt)

Bitumen is a black or dark-colored (solid, semi-solid, viscous), amorphous, cementitious material that can be found in different forms, such as rock asphalt, natural bitumen, tar, and bitumen derived from oil, which is referred to as petroleum bitumen. Currently, most of the roads globally are paved with bitumen. Today the world’s demand for bitumen accounts for more than 100 million tons per year which are approximately 700 million barrels of bitumen consumed annually.

Bitumen Application

Known for its adhesive and cohesive assets, bitumen is mostly utilized in the construction industry. Bitumen is applied on road paving because it is viscous when hot, but solid once it cools down. Therefore Bitumen operates as the binder/glue for pieces of the aggregate.
We are well aware of the complexity of bitumen as a product and in-depth knowledge and detailed understanding of the way the roads are built is crucial. Specialists in bitumen recognize bitumen as an advanced and intricate construction material, not as a mere by-product of the oil refining process.
The ultimate paving material (also referred to as hot mix asphalt concrete – HMAC or HMA) consists of about 93 – 97% mineral aggregate (stone), sand, and filler. The remaining percentage is a bitumen.

Bitumen is applied in the construction and maintenance of:

  • Reservoir and pool linings
  • Sound proofing
  • Pipe coatings
  • Cable coatings
  • Paints
  • Building Water Proofing
  • Highways
  • Airport runways
  • Damp proofing
  • Car parks
  • Racetracks
  • Tennis courts
  • Roofing
  • Dams
  • Tile underlying waterproofing
  • Newspaper Ink Production
  • Footways / Pedestrian Ways

1. Hot Rolled Coils

Hot-rolled coil is produced from semi-finished products, which are reduced to certain thicknesses by rolling and annealing and wound into a roll. Hot-rolled steel is used in e.g. for the manufacture of pipes, steel doors and tanks or is further processed into cold-rolled steel.

2. Cold Rolled Steel

Cold-rolled steel refers to low-carbon steel produced by a “cold rolling” method and processed at near normal room temperatures. Cold-rolled steel offers superior strength and machinability.

Cold-rolled steel sheets are commonly used for engineered products where tight tolerances, concentricity, straightness, and coated surfaces are required.

3. Coated Steel

Coated Steel is basically the product of continuous and highly automated industrial process for efficiently coating coils of metal with alloys like zinc, Aluzinc and polyester based paint. We deal in the following coated steel products;

i. Hot-Dipped Galvanized Coils:

It is produced by a process called galvanization where the iron and steel is coated with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C).

ii. Hot-Dipped Galvalume Coils:

Galvalume is a product of continuous and highly automated process for efficiently coating the coil surface with an alloy which is a combination of Aluminium (55%) and Zinc (43.5%) and a little amount of Silicon and other elements.

iii. Pre-painted galvanized or galvalume coils:

Pre-painted galvanized or galvalume coils, also known as pre-coated steel coil, coated steel, color coated steel etc., typically with a hot dip zinc and or hot dip aluzinc coated steel substrate. The term is an extension of GI or GL which is a traditional abbreviation for Galvanized Iron and Galvalume respectively.

Long steel Products

1. Wire Rods

Wire Rods are semi-finished product made out of billets by drawing process under hot rolling temperature. They are majorly used in fastner industries, roofing nail manufacturing and wire drawing.

2. Steel Billets

Steel Billets are also known as square bars are a semi-finished raw material that is used in manufacturing rebar, wire rod, and also seamless pipes. (from round billets)

3. STEEL DEBARS:

Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression but has weak tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar’s surface is often “deformed” with ribs, lugs, or indentations to promote a better bond with the concrete and reduce the risk of slippage. The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with deformation patterns. Other readily available types include stainless steel and composite bars made of glass fiber, carbon fiber, or basalt fiber. The steel reinforcing bars may also be coated in an epoxy resin designed to resist the effects of corrosion mostly in saltwater environments, but also land-based constructions. Bamboo has been shown to be a viable alternative to reinforcing steel in concrete construction. These alternate types tend to be more expensive or may have lesser mechanical properties and are thus more often used in specialty construction where their physical characteristics fulfill a specific performance requirement that carbon steel does not provide. Steel and concrete have similar coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal differential stress as the temperature changes

AGRO PRODUCTS

We are one of the leading movers of various agro products like Rice, Soya bean, Cashewnuts, Coco beans etc, recording volumes of more than 1.5million MT. We mainly supply to consumers in Middle east, Asia, China and Africa. Our key sourcing markets includes Africa, Middle East and Myanmar where we own and operate processing plants.

Soybean or Soya bean :
It is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses. Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh. Fat-free (defatted) soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals. For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many meat and dairy substitutes.Soy beans contain significant amounts of phytic acid, dietary minerals and B vitamins. Soy vegetable oil, used in food and industrial applications, is another product of processing the soybean crop. Soybean is the most important protein source for feed farm animals (that in turn yields animal protein for human consumption).
Rice:
Rice, is normally grown as an annual plant, although in tropical areas it can survive as a perennial and can produce a ratoon crop for up to 30 years. Rice cultivation is well-suited to countries and regions with low labor costs and high rainfall, as it is labor-intensive to cultivate and requires ample water. However, rice can be grown practically anywhere, even on a steep hill or mountain area with the use of water-controlling terrace systems. Although its parent species are native to Asia and certain parts of Africa, centuries of trade and exportation have made it commonplace in many cultures worldwide.

We have our own processing plant in Myanmar and exports to Asian and African markets in big volumes.
