EF Delta

EF Delta gives Eskan Faraz Delta a modern product and engineering presence for elevators, escalators, construction climbers, automation, and components. The platform combines an official product catalogue, technical documentation, project references, and bilingual content in a performance-focused Next.js experience. The catalogue ranges from complete vertical-transport systems to traction machines, doors, safety components, controllers, drives, drawings, specifications, and manufacturer authorizations. The redesign keeps that technical depth available without reproducing the navigation debt of the legacy catalogue.

Capabilities

Product families

Elevators, escalators, construction climbers, traction equipment, doors, control systems, and components have distinct discovery paths.

Technical documentation

Specifications, engineering drawings, manufacturer material, and authorization records support procurement research.

Bilingual engineering content

Persian and English routes make product and company information usable for local buyers and international partners.

Legacy content recovery

Useful catalogue material was extracted from the previous site, normalized, and rebuilt into a maintainable content model.

Project and company context

Product pages connect equipment to engineering capability, references, and the company behind supply and support.

Search-ready structure

Stable metadata, descriptive routes, and localization checks replace opaque catalogue pages with indexable content.

The operating challenge

Technical depth trapped in a legacy catalogue

Products, drawings, certifications, and company references existed, but inconsistent legacy pages made them difficult to find, compare, and maintain.

  • Fragmented product taxonomy
  • Mixed image and document quality
  • Weak bilingual navigation and search visibility
