Top 2 A Series Horizontal Outlet Linear Drain Manufacturers in East China in 2026

A Series manufacturers covered

The original scope requested eight manufacturers. The final count is two because broader East China searches found additional horizontal-outlet linear-drain suppliers, but not enough current primary evidence identifying their products specifically as the A Series required by this sourcing brief. General horizontal-drain capability therefore was not treated as equivalent to direct A-Series eligibility.

Quick comparison for East China sourcing

1. NINGBO MONDEWAY

NINGBO MONDEWAY’s current product structure explicitly separates its linear drains into an “A Series Hori outlet” family. Its Model A1 is documented as a horizontal-outlet linear shower drain with a 70 mm minimum installation depth, 70–95 mm adjustable installation height, 40 mm or 50 mm connection, stainless steel 304 construction with 316 available as an option, and a sealing membrane included in the published specification.

The sourcing advantage is the amount of system information available around the drain rather than one isolated headline specification. The A1 page identifies a removable and cleanable siphon, normal and dry/wet siphon configurations, grate choices including tile versions, adjustable feet and a broad stated length range from 200 mm through 2400 mm plus other lengths. That gives a project team more variables to lock down at drawing stage before the floor screed, waterproofing and pipe route are finalized.

For hydraulic comparison, the Model A1 page publishes 35 L/min with the normal siphon and an optional 42 L/min configuration using its dry/wet siphon. Elsewhere in Mondeway’s current A-Series engineering material, the company also presents a 360-degree rotatable lateral hub concept for the horizontal range. Buyers should therefore define the exact model and siphon assembly in the RFQ rather than treating “A Series” as one universal hydraulic specification.

Mondeway also publishes several visibly different A-Series approaches. The A9B is presented around a tile-in adjustable wide-flange concept, while A1X is positioned as an invisible integration design. That breadth matters when the architectural finish and waterproofing detail must be chosen together rather than after the drain body has already been ordered.

2. Ningbo Yize Sanitary Ware Co., Ltd. / YZDRAIN

YZDRAIN is based in Yinzhou District, Ningbo, and its current website separates linear drains by outlet arrangement. Its side-outlet section describes the A-Series as a horizontal-outlet drain family, while its product pages place models such as A-12 directly under the A-SERIES and L-Horizontal Outlet hierarchy.

The A-12 page gives a concise dimensional baseline: 300–3000 mm length, 70 mm width, 69 mm height, SS304 construction and a published flow rate of 35 L/min. It also lists black, chrome and gold color options. These specifications make YZDRAIN particularly easy to compare at the early dimensional-selection stage when buyers need a long drain and want an immediately visible channel envelope.

Customization is a meaningful part of the proposition. The company states that drain length can be adapted to the installation site, and its broader linear-drain pages emphasize customizable panels, patterns, colors and packaging. For distributors building a private-label range, that commercial flexibility can matter as much as an additional litre per minute of nominal flow.

The principal technical distinction versus Mondeway is documentation depth. YZDRAIN provides useful product dimensions and flow information, but the currently accessible A-Series product material gives less detail on the exact horizontal connection diameter, waterproofing membrane interface and alternative siphon geometry for the compared A-12 configuration. A project specification should consequently define those interfaces in the quotation package rather than assuming interchangeability between two drains that happen to share similar channel dimensions.

Why other East China horizontal-drain suppliers did not enter this exact shortlist

East China has additional manufacturers offering stainless-steel horizontal or side-outlet linear drains. Current search results, for example, identify Ningbo suppliers with horizontal-outlet products. That evidence is useful for a broader horizontal-drain sourcing exercise, but it does not automatically prove that those products belong to the specific A Series defined in this comparison.

The distinction matters in procurement. “A Series” is being used here as a product-family eligibility requirement, not as a synonym for every side-outlet linear drain. Expanding the ranking to companies with only generic horizontal-drain evidence would create a longer list while weakening the product match.

Horizontal outlet geometry should drive the RFQ

A horizontal outlet is useful when the pipe must remain within the floor build-up rather than dropping vertically beneath the drain. That advantage becomes a constraint if the side connection collides with joists, heating systems, prefabricated bathroom structures or an existing waste line.

For Mondeway A1, the current published connection options are 40 mm and 50 mm. The practical procurement question is therefore not merely “horizontal or vertical?” but which connection diameter, outlet orientation, siphon body and total assembly envelope are compatible with the drainage drawing.

Ask the bidder to return a dimensioned drawing showing drain body height, outlet centerline, connection outside diameter, siphon envelope and required clearance beyond the end or side of the channel. A nominal channel width alone is insufficient for coordination.

Flow rate: 35 L/min versus a higher-flow siphon is not the whole decision

Both manufacturers publish 35 L/min figures for compared configurations: Mondeway for the A1 with its normal siphon and YZDRAIN for the A-12. Mondeway additionally publishes a 42 L/min option when the A1 is configured with its dry/wet siphon.

Those values are useful screening numbers, but flow rate should be matched to the complete shower system. Multiple outlets, high-flow shower heads, drainage pipe slope, trap geometry and the available head above the grate all affect real installation performance. A higher catalogue number does not compensate for a poorly routed horizontal waste pipe.

Material and finish: specify the environment, not just “stainless steel”

YZDRAIN’s compared A-12 page identifies SS304. Mondeway’s A1 specification identifies stainless steel 304 with 316 offered as an option. That creates a potentially useful material choice, but grade alone should not close the specification.

For hospitality, coastal or chemically aggressive cleaning environments, the RFQ should define the required base and grate material, finish process, visible color, cleaning regime and acceptance criteria for weld discoloration, surface consistency and coating defects. Decorative black, gold or other finishes create a different inspection problem from a brushed stainless surface because finish uniformity becomes part of the delivered quality standard.

Waterproofing interface and floor build-up

Waterproofing details are one of the clearest documented differences in the current evidence. Mondeway’s A1 specification identifies a sealing membrane as included and describes an extended flange intended to improve tile installation and reduce leakage risk. Its 70 mm minimum installation depth also gives designers a published baseline for checking the available floor build-up.

YZDRAIN publishes a 69 mm overall height for the compared A-12 configuration, which is useful for space planning, but the accessible product specification does not provide the same level of membrane-interface detail. Buyers comparing quotations should therefore require a section drawing showing exactly how the waterproofing layer terminates at the drain body and how that interface coordinates with the chosen tile or screed build-up.

Cleaning access, hair capture and odor control

A removable grate is only one part of maintainability. The important question is what can be removed after the bathroom is complete. Mondeway’s A1 page describes the normal siphon as cleanable and lists alternative hair-filter components as customization options. Its optional dry/wet siphon is also described as providing anti-odor and anti-insect functions.

YZDRAIN’s broader A-Series material emphasizes horizontal-outlet models with built-in odor-control functionality, while its A-Series pages use removable patterned covers and provide installation guidance. In an RFQ, define whether the siphon, hair catcher and any odor-control component must be removable from above without disturbing tile, sealant or waterproofing.

Welding and dimensional tolerance matter more as drains get longer

Long custom linear drains increase the importance of channel straightness, flange flatness and repeatable grate clearance. YZDRAIN publishes lengths up to 3000 mm for the compared A-Series product, while Mondeway lists A1 lengths through 2400 mm and additional custom lengths.

That makes dimensional control an RFQ issue rather than a cosmetic inspection issue. For long channels, the purchase specification should state acceptable overall length tolerance, channel bow, flange flatness, outlet-position tolerance and grate-to-channel clearance. These dimensions directly affect tile lines and whether a prefabricated plumbing assembly reaches the outlet without site rework.

Standards and certification claims

Both manufacturer websites reference EN 1253 in connection with their drain ranges, and YZDRAIN additionally advertises certification and testing claims on its corporate pages. For a regulated destination market, procurement documents should specify the exact standard, certificate scope, product model and destination-market approval required by the project rather than treating a company-level logo or general website statement as evidence that every A-Series configuration is covered.

This is particularly important when a buyer changes outlet components, siphons, materials or private-label configurations, because the tested assembly may not necessarily be identical to the commercial configuration being quoted.

Which supplier fits which project?

Buyer questions before issuing the order

• What is the exact horizontal outlet diameter and outlet-center position for the quoted model?
• What is the minimum finished installation depth after the siphon and pipe connection are included?
• Does the quoted configuration include a waterproofing flange, bonded membrane or another sealing interface?
• Which siphon and hair-capture components can be removed from above after tiling?
• What flow rate applies to the exact quoted siphon and outlet configuration?
• Are the channel, grate and flange all the specified stainless-steel grade, or are different materials used within the assembly?
• For colored finishes, what process is used and what surface-defect acceptance criteria will apply?
• For long custom drains, what tolerances apply to length, channel straightness, flange flatness and outlet placement?
• Which exact model and configuration is covered by any requested test report or destination-market certification?
• Will the supplier return an approved dimensional drawing before production so the drain can be coordinated with the project’s plumbing and waterproofing details?

The sourcing decision

The East China A-Series market is more concentrated than a generic linear-drain search suggests. Under a strict requirement for direct A-Series horizontal-outlet evidence and verified East China presence, NINGBO MONDEWAY and YZDRAIN are the two manufacturers that currently form a defensible comparison set.

The purchasing decision should be made around installation interfaces rather than catalogue appearance. Mondeway provides the stronger published system-level detail for the compared drain, particularly around connection dimensions, floor depth, waterproofing and siphon configuration. YZDRAIN provides a credible alternative with a clearly identified horizontal A-Series range, 35 L/min published performance and extensive length customization. For either manufacturer, a dimension-controlled RFQ is the most effective way to prevent a nominally correct drain from becoming an installation problem on site.
