Quality Assurance

Dimensional Accuracy

Interchangeable: The parts supplied are marked and identified in a manner that the corresponding parts of a similar duct section can be interchanged.

Low leakage: The slip-tight technology ensures there is minimum leakage of air, thereby saving considerable energy and cost.

Aesthetics: Rolastar ducts ensure uniformity ‑ symmetry and dimensional accuracy. In an exposed area, we fabricate the ducting to camouflage the longitudinal seams and minimise the visibility of suspension rods. Durable surface finishes and colours are provided through pre-powder coated coils.

Training

Rolastar doesn’t just manufacture ducts. It ensures that people installing the ducting system are given proper training to ensure all standards are followed:

Documentation

Rolastar provides you with detailed documents related to the job along with each delivery. These include:

Parts Layout: Listing of all parts in sequence of assembly that should be followed.

Bills of Material: List of total quantity of each unique section.

Transverse Connectors Summary Report: Shows the type of connectors and quantity; 5% more cleats (C-SS joints) are supplied than the actual requirement to facilitate damaged/missing parts.

Area Summary Report: Shows area (in sq. ft.) for each duct part, sub-total and grand total (billable quantity).

Material Reconciliation Statement: Where the customer supplies raw material, a material reconciliation report is generated every month. Customer’s representative can undertake a physical inspection of balance of raw material at the factory any time he/she wishes.
These not only ensure an accurate inventory of the material received, but also cater to easy assembly and billing.

 

Indoor Air Quality (IAQ)

Whatever be the project – healthcare, offices, restaurants, malls – the quality of indoor air is of supreme importance. Rolastar ensures that your project has Superior Indoor Air Quality. If the duct system is prone to air leakage, the chances of air contamination is more. Our patented Rolamate 4-bolt flange system ensures that air leakage is bear minimum.

Further, our ducting provides for high-quality access doors at various locations which help clean and maintain the system. This further reduces the chance of air contamination.
