Sandblasting rooms are essential in industries like shipbuilding, petrochemicals, and aerospace. They provide critical surface preparation. However, these environments are extremely harsh. High-speed abrasives, dense dust, and noise pollution create challenging conditions. Therefore, sectional doors in these settings must offer outstanding sealing, durability, and resistance. Xinxiang Shengda Filtration and Purification Technology Co., Ltd. recently upgraded its sandblasting room with SEPPES industrial sectional doors, improving both safety and operational efficiency.
Core Challenges For Sectional Doors In Sandblasting Environments
Sectional Door Integrity: Challenges of Severe Physical Abrasion and Chemical Corrosion
Direct Impact and Abrasion from Blasting Media:
Abrasive particles like sand or steel shot constantly strike the door surface. This mechanical wear affects the panels, tracks, rollers, and seals. Coatings wear off, and scratches or dents may appear. Over time, the damage reduces both appearance and structural life.
Corrosion Risk in High-Humidity or Wet Blasting Environments:
High humidity or wet blasting leads to corrosion risks. Moisture mixes with dust or metal particles, forming corrosive substances. These attack guide tracks, torsion springs, and steel cores. Chemically aggressive materials from blasting further accelerate corrosion. This makes durable materials and protective designs essential.
Dust Contamination: Leading to Sectional Door Malfunctions and Seal Failure
Component Blockage and Accelerated Wear:
Fine dust easily enters moving parts—like rollers, tracks, motors, and sensors. Mixed with lubricants, it forms a grinding paste. This accelerates wear, causes jamming, and leads to faults like overheating or noise. System efficiency and reliability decline rapidly.
Loss of Sealing Integrity:
Dust erodes seals, causing cracks or deformation. Once seals fail, the door can’t contain dust or maintain pressure. This leads to leaks, environmental hazards, and higher noise levels. Poor sealing also raises energy use and maintenance costs.
High Maintenance Demands and Safety Hazards for Industrial Sectional Doors
Frequent and Costly Maintenance Requirements:
Compared to standard industrial doors, sandblasting doors need more frequent checks, lubrication, and part replacement. Wear occurs faster, raising downtime and labor costs. Maintenance becomes a constant task.
Increased Safety Risks:
Dust and wear can weaken motion and safety systems. Torsion springs or brakes may fail, leading to sudden drops. Dust in controls can cause short circuits or loss of safety interlocks. Regular inspections and reinforced safety features are essential.
Tailored Protection: PVC Curtains – The First Line of Defense for Sectional Doors
In response to the unique operational challenges of sandblasting environments, SEPPES collaborated closely with the operations team at Shengda Filtration & Purification Technology Co., Ltd. in Xinxiang City. Through on-site assessments and in-depth technical discussions, SEPPES developed a cost-effective and highly practical protective strategy specifically for their industrial sectional overhead doors.
Low-Cost and Efficient Maintenance
Compared to repairing or replacing a damaged industrial sectional overhead door panel, changing a worn PVC curtain is quick, easy, and low-cost. This not only reduces the long-term operational expenses associated with sandblasting facilities but also minimizes system downtime, allowing production to continue with minimal interruption.
A Smart Fusion of Flexibility and Durability
This mix of soft and hard protection provides a smart upgrade. It makes sectional doors more adaptable and long-lasting in abrasive environments.
Why choose SEPPES industrial lifting door?
SEPPES sectional doors are built for harsh sandblasting conditions. EPDM seals, thermal break joints, and corrosion-resistant springs ensure durability and insulation. Precision hinges and rollers support quiet and stable operation.
Advanced control systems offer soft start/stop, reducing mechanical stress. Safety features—like spring break protection and bottom sensors—ensure secure use. Expandable ports support interlocks, automation, and remote control. Choosing SEPPES means safer, more efficient operations with reduced maintenance needs.These are more videos.
