What type of explosives does Vastu store, transport or supply to customers?
Vastu Company stores, transports and supplies all types of bulk, package and initiation explosives for customers.
How will vibrations affect people or pets inside nearby structures?
he reaction to blasting vibrations depends on personal levels of tolerance and activity at the time of blasting. If inhabitants are busy at home and reside in a well-insulated structure that does not easily respond to vibrations, they may feel or sense very little. Noise may be “heard” while vibrations may not readily be perceived. However, if a resident is in a quiet environment or in a lightly-loaded structure, vibrations may be readily perceived.
Am I going to hear or feel the blast?
Yes, vibration and noise are inherent by-products of a blast, all of which can be controlled to minimize human perception. All blasts are carefully designed by our professionals and results are predetermined.
Why is a safe and efficient blasting operation necessary in quarrying, construction and mining?
Blasting is the most efficient way to fracture rock to be excavated by earth moving equipment. Drilling and blasting are essential components of most mining, quarrying and construction operations. These are the primary processes that impact every downstream unit of operation. A safe and efficient operation saves time and prevents property damage, harm to people and the environment.

What is light gauge steel framing in construction?
Light gauge steel, also known as cold formed steel is a popular building material that is used for creating both the structural and non-structural framing of a building. This thin and lightweight material is shaped into various profiles to create walls, floors, roofs and other elements for trusses. It is a popular material due to its high strength-to-weight ratio, durability and applicability to most types of construction projects.
Can you build multi-story buildings with LGS steel?
Yes, you can build buildings up to 4 stories tall using Light Gauge Steel.
What are the applications of LGS frames?

Light Gauge Steel Frames have a wide range of applications in various sectors, including:

Residential Buildings: LGSF is used in the construction of single-family homes, multi-story apartments, and townhouses.

Commercial Buildings: LGSF is suitable for office buildings, retail spaces, hotels, and other commercial structures.

Educational Facilities: Schools, colleges, and universities can benefit from LGSF’s fast construction and design flexibility.

Healthcare Facilities: Hospitals, clinics, and medical centers can be constructed using LGSF to meet specific healthcare requirements.

Industrial Buildings: LGSF is used for warehouses, factories, and industrial structures due to its strength and durability.

Why should I own an LGS constructed building? What are the benefits?
LGS constructed buildings can take a fraction of the time to build, and will help you save a lot of money in the overall construction process e.g. less labor, no weather delays, and reduced travel to site means a faster, cheaper build and equal if not better to the quality of an onsite build.
How much steel is used in a typical house built with light gauge steel?
A single story house using cold-formed steel for the wall and roof framing has approximately 16kg of steel per square meter of floor space. A two-story house has approximately 20kg of steel per square meter of floor space.
Is steel durable?
Galvanized Steel will not crack, shrink, splinter, creep, split, warp, swell or rot. Steel is impervious to termites and wood destroying insects.
How long does a LGS building last?

Light gauge steel constructed buildings can last a long time with proper maintenance and care.

However, the lifespan of a light gauge steel building can be affected by factors such as corrosion, weathering, and exposure to environmental factors such as salt, moisture, and extreme temperatures.

To ensure the longevity of a light gauge steel building, it is important to follow the manufacturer's maintenance guidelines and ensure, proper maintenance to avoid corrosion, leaks, and other problems that can reduce the lifespan of the building.

Will a light gauge steel frame rust?
No, the steel is hot dipped in an aluminum, zinc and magnesium alloy. Preventing rust from occurring.
Is a steel frame home energy efficient?
Yes. Steel framing can be designed to meet or exceed government energy efficiency standards. Steel framing is straight and true which helps prevent cracks due to shrinkage or warping; it prevents air leaks that result in costly loss of energy.
What is the cost of steel framing versus wood or concrete?
People assume that steel costs more than wood or concrete. The opposite is true. Steel is more cost-effective and dependable. When working with a steel frame building, other trades will take less time to finish their jobs as the frame is solid and square. Doors and windows will fit as they should with no adjustments. Framing with steel has less than 2% waste, whereas wood has up to 20% waste with splitting, warping and off cuts.
Will a steel framed home look different than other homes?
No. A steel frame home will look exactly like any other home. The same exterior finishes can be applied to a steel frame as those applied in standard construction.
Can a steel framed house be remodeled?
Yes. Since steel framing enables larger spans in the design of the home, fewer interior load-bearing walls are needed, making renovations very easy while allowing more flexibility in design.
Can a steel framed house be remodeled?
