The confirmed standard overall size for the DL-220 is W2000 x L2500 x H600 mm. These are product dimensions, not a substitute for the pit and installation drawing. Provide the loading-bay information and request the approved drawing before finalizing civil work. Rated load and electrical requirements should be confirmed for the ordered configuration.

Provide the dock height, vehicle and load information, forklift operating details, usage frequency and site drawings or photos. Explain any existing pit or loading-bay restrictions and provide the site electrical supply details. Ask for confirmation of the proposed configuration, rated load, installation dimensions and scope of supply in the quotation.

Review the complete loading-bay layout, including vehicle approach, opening dimensions, dock height and the equipment already installed. Share the proposed door, seal or shelter arrangement and any control-sequence requirements. Confirm the interfaces and installation drawings together so each product is selected for the same loading-bay conditions.

Provide the clear opening width and height, headroom, side room, available track space and site photos. Include the required operation method, site electrical supply, insulation needs and any viewing or pedestrian-access requirements. These details help define the configuration and scope of supply to be priced.

Available finishes and colours depend on the panel range and selected configuration. Provide a preferred colour reference, appearance requirements and information about the working environment. Ask SEPPES to confirm the available panel and finish options in the quotation before ordering.

SEPPES supplies industrial sectional door configurations for project selection. Review the industrial sectional door product page, then provide your opening dimensions, headroom, side room and operating requirements. The quotation should identify the panel, track and operator configuration proposed for your site.

Compare the proposed panel and track configuration, installation drawings, operator, controls, safety devices and after-sales support. Ask for project references relevant to your opening and operating environment. Confirm the scope of supply and installation responsibilities so you can compare complete quotations on the same basis.

The operator should be matched to the door dimensions, track arrangement, duty and required controls. Ask for the proposed operator specification and confirm the site electrical supply. Discuss manual operation and access requirements, control interfaces and maintenance arrangements before confirming the configuration.

Compare the proposed panel material, insulation construction and surface finish against your operating environment and project requirements. Request the specification for the selected model, including the panel thickness and available viewing sections where relevant. Avoid applying a single panel specification to every sectional door configuration.

Mention pedestrian access requirements at the enquiry stage. Ask SEPPES to check whether an integrated access-door arrangement is suitable for the selected sectional door, dimensions and operating conditions. Confirm the proposed layout, controls and safety requirements in the project drawing and quotation.

Include your project's fire-performance requirements in the enquiry. Ask SEPPES to confirm whether a suitable documented configuration is available and which product documents apply. The specification and quotation should identify the required performance; general panel descriptions should not be treated as evidence for a particular fire rating.

Door dimensions should be checked together with the panel arrangement, track layout, available headroom, side room and site conditions. Send the clear opening measurements and photos. Request confirmation of the selected configuration and an installation drawing instead of assuming that one maximum dimension applies to every sectional door.

Send the equipment information and the required operating sequence, including any interlock requirements. SEPPES can review the proposed door controls and interface requirements with the equipment supplier. Confirm the signal requirements, safety functions and commissioning responsibilities before the system is ordered.

Provide the required clear opening width and height, site exposure, traffic and available installation space. Size limits depend on the door structure and configuration. Ask SEPPES to confirm a suitable model and an installation drawing for your opening rather than relying on one maximum size for every high speed door.

Compare the actual opening frequency, required operating speed, traffic, sealing and environmental conditions. Also review the proposed materials, controls, safety devices and maintenance requirements. Use model-specific quotations for both options so the comparison reflects the same opening and intended duty.

Request written terms covering the warranty period, covered components, exclusions, spare parts and the process for obtaining technical support. Agree on installation and commissioning responsibilities, documentation and shipping arrangements. The terms for your order should identify the selected model and configuration; a general website statement is not a substitute for those details.

Focus on how the proposed configuration fits your traffic, opening dimensions, process and working environment. Compare the curtain or panel arrangement, controls, safety devices, sealing and maintenance access. Ask for the model-specific information that supports your selection and agree on the required functions in the order specification.

Describe the hygiene process, traffic frequency, sealing needs and any ventilation requirements. Curtain colour alone should not be used as the selection criterion. Discuss suitable curtain or screen options, opening controls and closure arrangements for the application, together with the facility's wider pest-management measures.

State the fire-performance requirements of your project before selecting the curtain and door configuration. Ask for documents that apply to the proposed material and complete assembly, where available. Fire-performance claims should be checked against the exact product specification rather than assumed from a general PVC door description.

Typical selection discussions include factory partitions, warehouse traffic openings, production areas and controlled workspaces. Suitability depends on opening dimensions, traffic frequency, environmental conditions and process requirements. Tell SEPPES how the opening is used so the proposed door and controls can be reviewed for that application.

Discuss how people, forklifts or automated equipment will approach the opening. Depending on the configuration, activation options may include push buttons, motion sensors, loop detection, pull switches or an equipment interface. Confirm the selected activation method together with the required safety devices and control logic.
