As a manufacturer with our own production base, we offer exceptional order flexibility and fully support global bulk wholesale purchases as well as high-end custom projects. MOQs vary across different product lines (such as casement windows, sliding doors, and curtain wall systems). We recommend contacting your dedicated sales consultant to get accurate MOQ information and bulk purchase discount policies for your specific product line.

A dedicated account manager will follow up on the production progress throughout the process and keep you updated with the latest information. Rush order priority production services are also available upon request.
Product Technology & Quality Assurance
Our products deliver exceptional energy efficiency performance. In particular, our high-performance thermal break aluminum windows and doors and low-energy passive window series feature multi-chamber insulation structures, premium thermal breaks, and energy-efficient insulating glass. This combination provides outstanding thermal insulation and sealing performance, effectively reducing building heat loss and gain, significantly lowering homeowners’ heating and cooling costs, and contributing to green and low-carbon building construction.
We always prioritize product quality and safety. All our windows and doors are manufactured in strict accordance with international advanced standards and have passed multiple global authoritative certifications. Our products achieve industry-leading levels in key performance indicators including airtightness, watertightness, wind resistance, sound insulation, and weather durability, meeting the building code requirements of different countries and regions.
We provide comprehensive installation support services to customers worldwide. All products come with detailed illustrated installation manuals and high-definition step-by-step video tutorials to help your installation team get started quickly. For large commercial projects or complex installation scenarios, we can also provide professional remote technical guidance. If necessary, we can arrange experienced engineers to conduct on-site training and full technical support.
International Shipping & Partnership
Yes, Olis offers door-to-door international shipping services worldwide. We have over 10 years of experience in international logistics operations and have established long-term strategic partnerships with top-tier ocean, air, and land transportation companies. We can customize the optimal shipping solution based on your project timeline and budget, ensuring your products are delivered safely and on time to any destination in the world.
We use industry-leading export-grade high-strength protective packaging solutions. Each product undergoes multiple layers of professional protection: glass panels are covered with special explosion-proof film and fitted with foam corner protectors, metal frames are wrapped in thickened pearl cotton, and the entire package is secured with high-strength wooden frames. This maximizes the structural integrity of products during long-distance ocean, air, and land transportation, preventing any shipping damage.
