Ensuring Low Maintenance for Pre-Engineered Building Structures

 

Pre-engineered buildings (PEBs) in India have surged in popularity across various sectors such as infrastructure, industrial, manufacturing, and warehousing due to their acceptance and performance. PEBs offer numerous benefits, propelling their widespread adoption in the construction market.

However, a well-constructed structure realizes its full potential when maintenance is proactive rather than reactive. Opting for a steel structure brings the advantage of requiring significantly less maintenance compared to other building materials. The longevity of a structure, along with its aesthetics and operational lifespan, depends on several maintenance-related factors.

Maintenance procedures vary depending on factors like building design, material specifications, leak-proof performance, and accessibility. Here are some best practices for maintaining a healthy structure:

Maintenance Frequency:

• The frequency of maintenance is determined by factors such as the internal and external environment based on location, environmental conditions, pollution levels, and building usage.
• Consider the age and condition of the building, as well as the long-term commitment to maintenance.
• Most maintenance activities should occur at least annually, except in areas with moderate to severe rainfall, where inspections are recommended post-winter and pre-rainy season.
• Regular roof cleaning should occur quarterly, with additional inspections and maintenance after severe storms.
• Buildings in coastal areas, exposed to industrial pollution or high humidity, require more frequent maintenance.
• Structures used for activities generating corrosive chemicals should undergo frequent maintenance.

Roof and Wall System Maintenance:

• Remove waste and small items using a soft nylon brush, while large items should be removed by hand to prevent roof panel damage.
• Wash away sand and dust with clean potable water and a soft nylon brush.
• Saline deposits should be washed with mild detergent added to the initial washing water for buildings in high pollution or marine environments.
• Oil, grease, tar, or wax can be removed with mineral spirits followed by detergent and water rinse, avoiding caustic or abrasive detergents.
• Clean translucent panels periodically using non-corrosive cleaning compounds to maintain light penetration, avoiding compounds containing ammonia or chlorine.

Accessories Maintenance:

• Regularly clean eave gutters, valley gutters, downspouts, and collector boxes, adhering to safety guidelines.
• Remove accumulated debris manually and use water hose pressure to flush out dirt.
• Unblock gutters and downspouts to prevent moisture buildup and rusting, ensuring proper drainage.

Maintenance of Buildings with Overhead Cranes:

• Lockout electrical on the crane before maintenance.
• Position the overhead crane between two rafters/trusses, never under one.
• Check high-strength bolts on crane beams after 45 days of operation and every three months thereafter.
• Inspect crane rails and end stoppers every three months for weldment and functionality.

By following these maintenance practices, the life expectancy and dependability of pre-engineered building structures can be maximized.
