Polyurethane Order Process and Delivery Technical Guide

The quotation process for architectural polyurethane elements establishes clear commercial and technical boundaries before manufacturing starts. Standard project quotes specify precise material parameters, including rigid closed-cell polyurethane density targets of approximately 150-220 kg/m³ (production target ~160 kg/m³) within an allowable 150-220 kg/m³ (production target ~160 kg/m³) range. Quotations maintain a defined validity window—typically 15 to 30 days—to account for raw material cost adjustments.

Manufacturing authorization depends strictly on two technical requirements:

• Formal written sign-off on technical specifications and dimensional schedules.
• Confirmation of the stipulated advance payment.

Once advance payment is confirmed, the order enters the production schedule. Technical performance standards, including thermal resistance ratings from -100 °C / +80 °C and water absorption limits under 1%, are integrated into factory batch management.

Polyurethane architectural products are distributed under an Ex-Works (factory delivery) commercial model. Under this arrangement, manufacturing finishes once elements pass quality control and are made available at the production loading bay. The client or designated freight logistics provider assumes responsibility for transit arrangements and site offloading.

Profiles are dispatched in factory-primed condition to protect the closed-cell structure during transport. Because high-density polyurethane profiles feature rigid structural characteristics, proper stacking and physical securing during transport are mandatory to prevent flexural stress or corner damage during transit.

Formal inspection at the time of delivery is a necessary step before accepting shipments on site. Project managers or installation supervisors must physically check incoming packages against delivery manifests and approved technical orders prior to signing carrier receipts.

Key reception verification steps include:

• Verifying total piece counts against technical project schedules.
• Inspecting outer profile edges, decorative reliefs, and factory-primed coatings for transit abrasion.
• Confirming that product dimensions match the specified project drawings.

If physical damage or quantity variances are detected during reception, details must be documented directly on the freight delivery documentation before the carrier leaves the site.

Correct site handling following delivery ensures polyurethane elements remain ready for assembly. Products feature a factory primer, making an additional field primer coat optional depending on final paint specification. Site storage requires flat, clean, and dry conditions to prevent mechanical deformation before installation.

Technical constraints must be strictly observed during preparation:

• Surfaces receiving profiles must be thoroughly clean, dry, and free of loose debris.
• Polyurethane columns and decorative pilasters are non-structural elements and cannot bear structural loads.
• Profile joint cuts must be executed at precise 45-degree miter angles using fine-toothed saw blades.

Installing delivered polyurethane profiles requires specific mechanical and chemical fastening protocols. Mounting relies on specialized polyurethane (PU) assembly adhesive applied to clean bonding surfaces. Standard silicone adhesives are strictly forbidden as they fail to form permanent structural bonds with high-density polyurethane.

Mechanical fixation using corrosion-resistant screws is mandatory to hold profiles in position while adhesive cures. Final finishing involves applying filler paste, sanding with 180-220 grit sandpaper, applying an optional primer coat, and finishing with two coats of paint. For exterior facade applications, UV-resistant exterior paint is mandatory to prevent environmental degradation.

Return policies for high-density polyurethane products align directly with formal contract terms and manufacturing conditions. Standard, non-customized stock items in original factory-primed condition may be eligible for return review within defined contractual timeframes, subject to restocking evaluations. Polure applies these standard terms to maintain clear accountability across all orders.

Return exclusions apply under the following technical conditions:

• Custom-manufactured profiles, modified dimensions, or non-standard moldings.
• Elements that have been cut, installed, sanded with 180-220 grit media, or field-painted.
• Products damaged due to improper on-site storage or incorrect handling post-delivery.
