Frequently Asked Have Any Questions? Technical & Authoritative

I. Structural Engineering & Design

We primarily use high-tensile 6061-T6 for structural frames and 6063-T5 for intricate profiles, ensuring a perfect balance of strength and surface finish.

Profiles are selected based on the clear span: Small (<6.5m), Medium (6.5–9m), Heavy-Duty (9–16m), and Ultra-Span (16–25m).

While they are engineered for permanent use, their "retractable" nature often classifies them as non-permanent structures, which can simplify the permitting process.

Yes. We offer wall-mounted, roof-mounted, or completely freestanding configurations depending on your site’s architectural constraints.

With proper maintenance, our aluminum frames have a lifespan exceeding 25 years, while glazing panels typically last 15–20 years.

All profiles undergo high-micron powder coating or anodizing, meeting international marine-grade standards for corrosion resistance.

No. We use internal corner connectors and hidden fastening systems to maintain a clean, high-end aesthetic.

II. Wind, Rain, and Snow Loads

Our standard systems are rated for up to 100–120 km/h, though we can engineer custom reinforced versions for hurricane-prone regions.

We calculate the "Snow Load" based on your specific zip code. Our Heavy-Duty profiles are designed to support several dozen kilograms per square meter without deformation.

The structure should be fully closed and locked during high winds or snowstorms to ensure the structural "box" is rigid and secure.

Integrated gutter systems and internal drainage channels within the profiles direct water away from the living area to designated discharge points.

Yes. We utilize multi-layered EPDM seals and silicon gaskets to ensure a watertight seal between moving segments.

No. Our tracks feature "Anti-Lift" mechanical locks that prevent segments from being detached by upward wind pressure.

III. Motorization & Manual Operation

We utilize high-torque, synchronized tubular motors (e.g., Somfy or similar industrial grades) with IP65 weatherproofing.

Yes. Most systems include a manual override crank or a battery backup option.

Absolutely. Our smart-hub integration allows for control via iOS/Android apps, Amazon Alexa, or Google Home.

We offer wind, rain, and sun sensors that automatically close or open the system based on real-time weather changes.

The motors operate at a "whisper-quiet" level, typically below 50 decibels.

Depending on the number of segments, a full cycle typically takes between 45 and 90 seconds.

IV. Glazing, Shading & Lighting

Polycarbonate is virtually unbreakable and lighter (ideal for large spans), while tempered glass offers superior clarity and scratch resistance.

Yes. Our polycarbonate panels feature a co-extruded UV-protection layer that blocks 99% of harmful rays and prevents yellowing.

Yes. We offer dimmable LED strips or "spot" lighting integrated directly into the aluminum profiles with hidden wiring.

We offer integrated honeycombed blinds or retractable fabric under-roof systems for thermal and glare control.

Twin-wall polycarbonate or Double-Glazed glass provides excellent insulation, allowing the space to be heated efficiently.

No. Our tracks feature "Anti-Lift" mechanical locks that prevent segments from being detached by upward wind pressure.

V. Site Foundation & Preparation

A level, reinforced concrete pad or a structural steel/timber deck is required to ensure the tracks remain perfectly parallel.

The tracks require a tolerance of less than 3mm over a 5-meter span to ensure smooth motorized movement.

Yes. We offer "Flush-Track" designs that sit level with your flooring to eliminate tripping hazards.

While the track itself is level, we recommend a 1% outward slope for the surrounding patio to assist with surface water runoff.

VI. Production & Quality Control

All systems are fabricated in our specialized facility in Jiangsu, using precision CNC machinery to ensure millimeter-perfect accuracy.

Yes. Every structure is fully assembled and tested for mechanical movement before being disassembled and packed for shipping.

Yes. We offer a full range of RAL colors in matte, gloss, or textured finishes.

Production usually takes 6–8 weeks, depending on the complexity and customization requirements.

VII. Logistics & Shipping

We use custom-built steel crates or reinforced wooden boxes with protective foam layering to prevent transit damage.

We offer EXW, FOB, and CIF terms. For North American and Australian clients, we often assist with DDP (Delivered Duty Paid) logistics.

A standard sunroom crate can weigh between 800kg and 1,500kg. A forklift is required for offloading at the site.

We provide the Bill of Lading, Commercial Invoice, Packing List, and Certificates of Origin.

VIII. Installation & Maintenance

While we provide detailed manuals, we highly recommend professional installation due to the weight of the segments and electrical requirements.

A typical team of 3–4 people is recommended for most mid-sized enclosures.

Tracks must be kept free of debris (leaves, sand). We recommend a monthly vacuuming of the tracks and a semi-annual lubrication of the rollers.

Use a soft cloth or sponge with mild soap and lukewarm water. Avoid abrasive chemicals or high-pressure washers.

We offer a 10-year warranty on the structural frame and a 5-year warranty on the motors and glazing.

IX. Product-Specific FAQ

Retractable Sunrooms

Yes, when equipped with insulated glazing and a climate control system (AC/Heating).

Legally, it is often considered a "covered patio," but it provides the functionality of a full room extension.

Retractable Pool Enclosures

Yes. The "greenhouse effect" can increase water temperature by 5–10°C, significantly extending your swimming season.

Our aluminum and stainless-steel hardware are specifically treated to resist the corrosive humid environment of a pool.

Yes. All segments are lockable, acting as a high-security child-safety barrier when closed.

Retractable Roof Systems

We can achieve spans up to 25 meters, making them ideal for stadium or large commercial rooftop applications.

Yes. You can stop the segments at any point to control the amount of airflow and sunlight.

The system includes a manual release, and the motor itself can be replaced without dismantling the entire structure.

X. General Inquiries

Provide us with your site dimensions (Width x Length x Height), location, and preferred glazing type.

Yes. For every project, we can provide a stamped engineering report to support your building permit application.

No. Sunrim utilizes proprietary high-specification extrusions and custom-engineered hardware for a higher level of durability and span capacity.
