Choosing an automatic door supplier starts with the equipment and work being purchased. Identify who makes the operator, supplies the leaves, installs and commissions the system, and handles subsequent service. A brand name, dealer authorisation and a performance figure answer different questions. This guide uses Record information as an example and provides a supplier-review method; it does not rank automatic door brands or present this site's operator as a manufacturer.
Manufacturer, dealer and installer describe different roles
A request for an “automatic door manufacturer” may concern an operator only, a complete glazed entrance, or refurbishment with installation and support. Those are different scopes. A company name does not establish which work it will perform for the project.
Use the following roles to structure the enquiry. One company may undertake several roles, but each responsibility still needs a clear answer. The table does not prescribe a particular procurement arrangement or require five separate companies.
| Role or scope | Information to request | Related delivery evidence |
|---|---|---|
| Operator and component manufacture | Exact equipment brand, model, version and source | Applicable product documents, identification and supply information |
| Leaves and associated fabrication | Who supplies leaves, profiles, hardware and the relevant construction | Leaf schedule, dimensional and weight basis, agreed drawings |
| Distribution and supply | The supplier's role and the scope of any authorisation or source statement | Supplying party, relevant documents and proposed equipment list |
| Installation and system coordination | Who installs, configures and coordinates with other systems | Site scope, personnel, changes and verification records |
| Maintenance and fault handling | Contact route, equipment covered, work included and escalation | Service arrangements, maintenance information and repair handover |
Knowing the product manufacturer does not identify every party responsible for the entrance. Retain both the equipment source and the project contacts. A brand presentation without a delivery scope leaves important questions open.
Establish what the quotation actually supplies
Automatic sliding doors, sensor doors and glass automatic doors describe different aspects of an entrance. One term concerns movement, another activation or leaf material. None establishes whether a quotation includes the operator, leaves, protective equipment and site work.
Prepare the intended door arrangement, structural opening and required passage dimensions, moving-leaf information and weight basis, available installation space, operating requirements and relevant interfaces. Then ask each candidate to identify the equipment and work proposed against those inputs.
Record's public System 20 information describes a linear sliding system, while sensors are also described in a separate product category. This helps distinguish the subjects of the documents. It does not establish a complete project configuration or the suitability of an unidentified part. The international enquiry guide provides a related scope worksheet.
Match a claim to the evidence for that claim
Statements about origin, durability, quiet operation, safety and service are not interchangeable. Ask the supplier to state the exact claim and identify the subject and conditions of its evidence. Do not turn a missing answer into a finding that a product is defective, or an informal explanation into a verified result.
| Claim in a proposal | Evidence to request | What does not follow automatically |
|---|---|---|
| Imported equipment or stated origin | Identification of the proposed equipment or batch and the related source information | Brand history or packaging alone does not establish the source of every delivered component |
| Low failure rate, durability or long life | Exact model, data subject, conditions and statistical or test basis | Test cycles cannot simply be divided by daily use to establish actual service years |
| Quiet operation | Measurement subject, leaf/configuration, method and environment | An operator figure alone does not establish the sound level of the completed entrance |
| Safety or a specialist application | Relevant performance documents, scope, installed configuration and project requirements | A component marking or one document is not acceptance of the complete entrance or intended application |
| Authorisation and support | Named parties, validity, scope and actual service arrangements | Dealer status does not by itself establish stock, a national warranty network or an attendance time |
These are evidence questions, not a universal document checklist. A supplier should explain which records apply to its proposal and which matters remain unresolved.
Read authorisation alongside the project scope
Check the named company, authorisation relationship, period of validity and matters stated in the document. Separately identify who supplies the proposed products, performs site work and handles maintenance. An authorisation record describes a relationship; an equipment list and project agreement describe the actual delivery.
The distributor-certificate image published on this site names 河南联同创智能科技有限公司 and displays a validity period from 1 June to 31 December 2026. These are visible document fields. The image is a reference for further checks, not grounds to extend product, territory or service commitments beyond the relevant documents and project agreement.
Ask each candidate to identify the party handling the order, delivery, installation and subsequent problems. Keep the current equipment proposal, contact details and responsibility record together. A certificate screenshot or a website footer is not a complete answer to those questions.
Compare the outstanding questions before comparing totals
Retain the date and version of each proposal. Place equipment identity, leaves, activation and protection, installation, documents and service alongside each other. Do not assign a technical pass or fail to a proposal whose scope is still undefined.
Useful review statuses include “provided and identifiable”, “described but evidence outstanding”, “dependent on another party” and “not answered or awaiting site confirmation”. Attach an evidence reference and a person responsible for the answer. Differences should remain visible until they are resolved or consciously retained in the scope.
For example, an operator-only offer and an offer including leaves, protective devices, installation and handover records describe different deliveries. The example illustrates comparison; it is not a customer case or a market-price statement. Request a common basis before using the totals to support a purchasing decision.
Unconfirmed retained parts, locking behaviour or external interfaces should not become “resolved” merely because a quotation has been accepted. Record the remaining question and how it will be answered.
Installation and support need their own answers
Equipment supply does not automatically include installation. A working telephone number does not establish a promised attendance time. Confirm survey, transport, site installation, configuration, verification, training and document handover, including the site conditions and other parties needed to complete them.
Separate initial response, scheduling, attendance, part delivery and restoration of operation. One milestone cannot stand in for another. Warranty arrangements also need the equipment or work covered, period, responsible party and agreed conditions; a shared product brand does not establish identical terms for every channel or project.
For another country, state the destination, local partner, site conditions, travel arrangements, document language and escalation route. An English product page is not evidence of an installation team or a service network in that country. These matters require a project-specific answer.
Leave a record the next person can use
Retain the installed equipment and parts list, applicable documents, agreed proposal, changes, verification results, training information and service contacts. A later maintenance party needs to know what was installed, what changed and which questions remain open, rather than inherit only a price and promotional photographs.
Protection, access control, locking and emergency functions need coordination by the relevant responsible parties. Do not open covers, change wiring, simulate a fire input or use a person in the closing path to compare competing suppliers. The door-safety guide explains the scope of evidence and return-to-service records.

It is not a manufacturer ranking, an approved-supplier list or an acceptance certificate. The Chinese supplier guide provides the corresponding Chinese sheet.
Source scope and this site's role
This guide was reviewed on 1 November 2026 using Record's public System 20 product information, sensor category and the certificate image on this site, alongside the previously reviewed model, document, component and service references. Product information supports identification of the document subject; the image supports reading its visible fields. This review does not compare the performance of all brands or establish a common failure rate, service life, sound level or service coverage.
The site operator is 河南联同创智能科技有限公司 in Henan, China. Contact Manager Wang at +86 13271597000. Contact address: 11A1-16, Huanancheng, Longhu Town, Xinzheng, Zhengzhou, Henan, China. Chinese address: 河南省郑州市新郑市龙湖镇华南城11A1-16号.
This site provides Record information and project enquiries. Actual supply, stock, installation, attendance, price and warranty responsibilities require a specific reply and agreement. The contact address is not evidence of a production facility or inventory. An enquiry from outside China needs a separate answer on destination-country arrangements.

Frequently asked questions
Must an automatic door be purchased directly from its manufacturer?
Manufacture, distribution, installation and support may be undertaken by one party or several. Check actual equipment source, supplier role, personnel and work scope. A role title alone does not establish suitability, and a dealer should not be represented as the manufacturer.
Can an automatic door brand ranking decide which proposal to select?
First align the door arrangement, configuration, installation conditions, documents and service scope. A ranking without comparable evidence does not replace project selection. This guide provides review questions rather than market-wide brand positions.
Does dealer authorisation include installation and nationwide warranty service?
Those commitments do not follow from authorisation alone. Check the named parties, validity and stated scope, then separately confirm installation, maintenance, warranty and arrangements for the project location.
How should origin, durability and noise figures be reviewed?
Ask for the proposed equipment identity, data subject, conditions and evidence. Brand history does not replace source information, cycle counts do not directly establish service years, and an operator figure does not automatically describe the installed entrance.
Why are two complete automatic-door quotations not always comparable by total?
Operators, leaves, activation and protection, interfaces, site work and service may differ. Record included, extra and unresolved items before comparing, so different deliveries are not treated as identical proposals.
Does a completed supplier worksheet mean that purchasing or acceptance is approved?
No. It is a blank tool for collecting answers and evidence. Unresolved items still need the responsible parties, and selection, technical verification and acceptance require the applicable equipment documents and project requirements.
Reference information only; the manufacturer's official data takes precedence.
