Steel & Zinc-Iron Entrance Doors for Trade Buyers
Compare steel and zinc-iron entrance door configurations for distributors and projects: sheet thickness, frame, dimensions, locks and quotation requirements.
TEENPAI helps distributors, building-material retailers, contractors and OEM buyers select metal entrance doors. The models shown here have recorded steel or zinc-iron material information. Check each product specification and the agreed order configuration rather than treating all metal doors as the same material.
How to compare steel door specifications
Check door-leaf sheet thickness, frame sheet thickness and overall leaf thickness separately. They describe different measurements. For example, the published Shangjie configuration lists a 1.0 mm leaf sheet and a 2.0 mm frame sheet. These figures apply to that configuration and are not a specification for every door.
Locks and opening direction
Provide inward or outward opening, handing and the required lock configuration. Read the model-specific hardware information. For a smart lock, also confirm its power supply, operating language, lock-body dimensions and maintenance arrangements.
Requesting a distributor or project quotation
Include the model, quantities by size, frame requirements, finish, locks, packing and destination country in one request. Compare quotations against the same agreed configuration. Prices, minimum order quantities, production timing and trade terms need order-specific confirmation.
Materials and project requirements
Steel, zinc-iron alloy and cast aluminium are different material descriptions. A cast-aluminium-style finish does not establish a cast-aluminium door leaf. An entrance door is not automatically a certified fire door. Share any fire, security-rating or acceptance requirements before quotation.
Buying questions
Does 1.0/2.0 describe the overall door thickness?
No. In the relevant published configurations, it describes the 1.0 mm leaf sheet and 2.0 mm frame sheet. Check overall leaf thickness separately.
Can every model use the same size range?
No. Check the dimensions for the selected model and clarify which part of the assembly is being measured.
Can I discuss private-label supply?
Yes. Discuss OEM branding, designs and configurations with export sales. Feasibility, quantities and costs must be confirmed for the order.
